Do you dream of increasing your living space, but don’t know which extension to choose? Beautiful and functional extension allows you to make your home more spacious by adding the necessary square meters. To find the veranda option that meets your expectations and the architecture of the place, use photo ideas for house extensions.

How to make an extension to a house?

if you have a private house, then in most cases you can always increase your living space thanks to an extension. Do you want a custom porch tailored to your needs? Consider the following photos of home facades to make your dream come true.

Based on the budget allocated for the extension

Extending your home can be expensive, depending on the project you're considering. However, it is always possible to find a solution for all levels of funding, even within the minimum budget. For more or less well-endowed projects, it would be better to prefer installing a veranda for the construction of a large extension. Attic development projects are in the middle of the price range, provided they do not have to deal with too many structural issues such as access etc. Finally, the largest expansion projects overseen by the architect are in the high price range.

Choosing the right option

Construction of a veranda requires organization. You should definitely find out from specialists what is allowed or not to be done in your home, consult regarding the extension, voicing your desires - additional room all year round, relaxation area, kitchen, spa, etc. Be sure to follow the technical or regulatory details that need to be taken into account. You will have a clear idea of ​​what kind of extension can be built by forecasting the family budget.

Lots of possibilities

Home extension or extension: a solution to expand space without huge investments. Create new bedroom, study, new kitchen or living room for home reorganization. Modern architects work for most extension projects. But be careful as any expansion project, be it simply adding a room, installing a veranda or implementing an elevation, must be carried out in compliance with certain rules.

Extension to a private house: several solutions

You can expand the area of ​​the house thanks to an extension, which can be separate from the common rooms, acting as a separate corridor, or complement the space of the living room.

Side room extension

This is the preferred solution for owners of fairly spacious land. A side room extension allows you to add volume to your home with priority to create or change area, providing a connection between two rooms (old and new). You can then let your imagination run wild when choosing the style of new construction.

Entrance corridor

If you maintain separation of the extension from the main living environment in the house, then the veranda will be in the form of a cozy corridor, which is especially useful in winter due to the warmth from the street. Being a less used room on winter evenings, you need to heat this type of extension to a minimum.

Living room addition

Unless you separate the veranda from the existing enclosure, for example by knocking down a wall to create a larger space, heating will need to be provided, even with good insulation. The design of the veranda also depends on the destination. An attached room can complement the kitchen or living room.

Functional extension to the house

The use and placement of the porch will also affect the overall layout of the house. In some cases, you may need to modify some of the existing rooms to make the extension more functional. Consider photo examples that allow you to consider several options for verandas for living and relaxing, both open and closed type. Both options will help create bright and comfortable spaces that make it easier daily life. The original extension of the house optimizes the living comfort of all family members.

Closed extension

The closed type of extension perfectly serves as an additional room, if you take care of it interior design and insulation. Such an addition will not only harmoniously decorate the facade of the house, but will also increase the comfort of the living interior space.

Open veranda

If you want to beautifully decorate the entrance to the house, increasing the porch area, creating a comfortable seating area on outdoors V summer time years, then a non-glazed extension will help you with this. The veranda can be arranged garden furniture, where you will enjoy the peace and tranquility of the surrounding garden. Such extensions are especially popular for country houses and country houses.

Verandas are the easiest option for expanding a house

Building a veranda is relatively the easy way change the square footage of your home. Pouring out cement board, and the porch becomes ready for assembly by the contractor. The wall to which the veranda adjoins must be reinforced, since it is load-bearing. The modern extension is a high-class structure with embellished gables whose charm is sure to attract everyone. You can choose both standard versions of the veranda and unusual ones, connecting the room with the living room or dining room. For good comfort, underfloor heating, blinds and year-round maintenance are necessary.

Expanding your home with an extension is a solution that will bring additional value to your home in case of resale, but will also allow you to improve your living conditions. To carry out this work, it is necessary to choose the most suitable project, remembering to comply with the necessary administrative procedures and other urban planning restrictions. An extension to a house is a fairly commonly used solution for expanding living space. If the architecture of the building and the area of ​​the landscape allow for such an addition, then be sure to take this chance.

For a number of reasons, some private houses and cottages need additional premises. A room for a kitchen, a bathroom or a closed veranda - everyone has their own plans for an additional extension. This article will help you understand how to build a high-quality extension to your house yourself.

Premises requirements

It is possible to make an extension to your house with your own hands. It's best when appearance such a room will be combined with the house itself. But this factor is not always the most important; the main thing is that the extension is durable and of high quality. Considering the lightness and reliability of the structure, many choose a frame extension to the house. It is inexpensive, reliable and quickly erected.

Think through all the details in advance. Each type of room has its own nuances. The veranda does not provide heating, unlike the additional room. If it will be a kitchen or bathroom, lay utilities and pipes before construction begins, take care of future insulation and waterproofing.

Choose the best one in advance optimal size extensions

Construction of the foundation for the extension

The most important point in the construction of an extension, arrangement is considered. If the owner took part in the construction of the house, he knows all the nuances of the size and design of the old foundation. When purchasing already finished house such information may not be available. In this case, you need to dig a hole yourself near the wall of the house and take measurements of the foundation, its depth and determine the nature of the soil.

Strip foundation

The strip foundation is poured in the shape of a rectangle in two ways: closed, and also in the shape of the letter “P”, open.

There are several options for connecting the foundations of the house and the extension:

With a closed method of pouring concrete:

• install a sheet of expanded polystyrene 50 mm thick between the foundation strips. It will be part of the formwork when pouring concrete. After filling, the remaining gap must be sealed with sealant;
• connect the ends of the foundations to each other reinforced frame. At the end of the base of the house, drill holes in two staggered rows. Place reinforcing bars there, which you will later connect to the frame of the extension’s foundation;

With the open filling method:

• pour the foundation of the extension in the shape of the letter “P”, and install insulation on the crack in the house;
• To connect buildings, drill holes for reinforcement only at the junction of two foundations.

Columnar foundation

If your extension is small in size and weight, a columnar foundation is a good alternative to a strip foundation. Such a foundation is suitable for the construction frame extension at high groundwater levels.

Stages of construction of a columnar foundation of an extension:

1. Dig holes deeper than the freezing level of the soil; the distance between them should not exceed 1.5 meters.
2. Place a bed of sand and gravel at the bottom of the holes. Compact the material well and lay the roofing felt.
3. Prepare strong formwork from boards or plywood for each pit.
4. Reinforce the formwork using 4 bars of periodic profile reinforcement.
5. Fill in concrete mixture into the formwork, wait for complete hardening. Remove the formwork and make a grillage.

Installation of the base floor of the extension

For a columnar foundation, a wooden floor base is suitable. When constructing a strip base, there is a choice between wooden and concrete floors. If the extension room will be used as an additional room, care must be taken to ensure high-quality thermal insulation and a flat surface.

When comparing the properties of durability and strength, a concrete floor takes a leading place, but a wooden house has good heat and sound insulation. Wood beams are also faster and easier to install.

Concrete floor

Before pouring the floor, consider the soil characteristics of the extension. Concrete floors are not installed on moving soil. If the room is never heated, over time concrete structure may become deformed.

The construction of a concrete floor includes the following steps:

1. After the strip foundation has completely dried, dig out the top layer of soil 25-35 cm inside the structure and compact the surface of the earth.
2. Fill up river sand 10 cm thick. Compact and lay two layers of roofing material in a checkerboard pattern.
3. Fill in expanded clay to a thickness of 15 cm. Install special beacons or bricks around the perimeter of the expanded clay cushion. Place a building level on top and level the base of the floor. If the extension is being built for a summer cottage, it is not necessary to lay the reinforcing mesh.
4. Pour in a high-quality concrete solution, level it using the rule and wait for complete hardening.

Floor on wooden beams

For a columnar foundation structure or frame extension, it is necessary to install load-bearing logs. They act as the skeleton of the building, evenly distributing the load throughout the entire extension.

The beams are laid using the following technology:

1. Install and secure a double layer of waterproofing on the foundation pillars.
2. Before installation, treat wooden beams with a special antiseptic.
3. Lay the floor beams on the foundation pillars and secure with corners. Fasten the beams together in the same way.

Construction of extension walls

The walls for the extension are selected according to similar material with the house itself. The most common materials for building walls are brick and wood.

To connect the walls of two buildings, it is better not to use a rigid connection. The difference in age between the old and new walls can lead to uneven settlement and cracks. Leave a distance of 2-3 cm between the walls of the building, which after erecting the walls, fill it with polyurethane foam.

Frame walls

Necessary materials for construction frame walls is high-quality wood and mounting angles. We install the frame to the base of the extension on load-bearing elements previously installed.

1. Install the corner posts first, securing them with reinforced steel corners. Fasten the intermediate beams either using the full cutting method, or in the same way as the corner beams.
2. Additionally, secure the intermediate beams with temporary bevels, which must be removed after the walls of the extension are completely installed.
3. Secure the upper tier of the frame in the same way as the lower part. For better strength, each beam can be fixed with braces on both sides.
4. After installing the frame, sheath the external walls of the extension using wooden planks or sheets of plywood.

Brick walls

The technology for constructing brick walls includes the following stages:

1. Before starting construction, level the foundation using cement-sand screed. Lay a layer of roofing material on top for waterproofing. Lay the first row of bricks on roofing felt without the help of mortar.
2. Attach small diameter reinforcing bars to the brick rows of the main house. Drill holes every two rows of brick. In progress brickwork extension, protruding reinforcement from the walls of the main house will end up in the joints between the new bricks laid.
3. Stretch a rope parallel to the wall, which will help build the brick rows as evenly as possible. Between every third row of bricks you can lay reinforcing mesh, which will reduce shrinkage and increase the strength of the walls.

After erecting the walls, tie them at the top with a concrete belt. Pour concrete mortar into the constructed reinforced formwork.

Extension ceiling and roofing

The roof of the extension should also be in harmony with the main building. Select high-quality roofing material and carry out construction calculations sizes and angles of inclination. For slate and metal tiles optimal angle tilt from 30-40º, for metal profiles – from 20º, for corrugated sheets – from 12º.

The technology of the roofing process includes the following stages:

1. Install ceilings in the form of wooden beams on the walls. Secure them with corners at a distance of 50-70 cm from each other. If the walls are made of brick, embed the beams in concrete. Then cover them with boards and insulate them.
2. Lay the Mauerlat around the perimeter of the side walls. It will serve as a support for the rafters, which are erected at a distance of no more than 70 cm from each other. There should be the same spacing between the rafters and floor beams. To protect the walls from water, the rafters must extend 30 cm beyond the walls.
3. Place a special waterproofing film on the rafters and install lathing in the form of horizontal boards.
4. Place the selected roofing material on the sheathing.

Insulating the extension from the inside

If the extension room will serve as a living room, it is important to take care of high-quality thermal insulation of the floor, ceiling and walls. For better ventilation, the concrete walls of the room are insulated from the outside. Suitable material foam or mineral wool is used.

Floor insulation on beams

To provide insulation and floor covering, a subfloor is installed. Cross boards are laid on the supporting joists of the extension.

Further technology includes the following steps:

1. Lay a waterproofing film on the subfloor, on top of which install additional joists.
2. To insulate the floor, lay several layers of polystyrene foam or mineral wool between additional joists.
3. Lay another layer of vapor barrier on top, on which sheets of oriented strand board will be laid.
4. Install fine coating floor.

Concrete floor

We insulate a concrete floor in the same way as a wooden floor. On concrete screed a layer of waterproofing film is laid. You can install thick logs and cover half their thickness with expanded clay. This will increase the level of thermal insulation. Next, mineral wool, a second layer of film and OSB boards are laid according to the same scheme.

Frame walls

To insulate frame walls, a sheathing of wood blocks is created around the perimeter of the walls and ceiling. The insulation of the extension is carried out using rolls of mineral wool. Thickness wooden block and rolls of cotton wool should be the same. The distance between the bars corresponds to the width of the insulation roll.

After thermal insulation, we waterproof the surfaces. The waterproofing film is laid overlapping and nailed to the sheathing bars. Next, the room is decorated with plastic, sheets of plywood or wooden paneling.

Brick walls

The brick walls of the extension can be insulated outside and inside. Internal insulation is carried out in the same way as insulation of the walls of a frame extension. For external insulation brick wall foam is often used. The insulation is glued to the outer walls of the building using a special glue in a checkerboard pattern.

The slabs are additionally reinforced with dowels, which are installed in the walls. A reinforcing mesh is applied on top and final plastering is carried out.

Sooner or later, every homeowner begins to think about expanding their living space. And here many questions arise, the main one of which is how to do this? Nowadays, the range of materials on the construction markets is quite impressive, which means that there are plenty of options for how to increase housing. Today we will look at some of them. Let's find out what an extension can be like (projects and photo examples will help with this), and also try to understand how complex such construction can be. It wouldn’t hurt to learn how to do this kind of work yourself.

You can find it on the Internet various projects extensions to the house. And before starting such construction it is worth familiarizing yourself with them. This will allow you to adopt any solutions and then add your own. Only then can you get a unique structure that will not only be, but will also increase your living space.

Many may say that such construction is too labor-intensive and practically impossible to do with your own hands, but this is a misconception. At the right approach and learning all the nuances is not so difficult, although you will have to face some difficulties. But, as they say, the eyes are afraid, but the hands do. But as a reward you can get not only a do-it-yourself extension to wooden house, but also satisfaction from the work performed. In addition, the money saved on paying specialists will not be superfluous.

Let's consider various options extensions in general terms, as well as examples of similar work done with their own hands by ordinary home craftsmen without any experience.

Solutions for adding a veranda to a wooden house in photo examples

This type of construction is quite relevant for summer residents who like to sit in the evenings over a cup of tea with family or friends. After all, on fresh air It’s much more pleasant to communicate than indoors. In addition, it is possible that the veranda will be designed in such a way that it is possible to install. This will protect it from snow, and will also add warmth to the house itself.

Another advantage of such a building is that you can spend it there in the winter. In this case, it can even be used as an additional room. But this is more suitable not for summer residents, but for owners in the private residential sector who live in the premises for a whole year.

The material for such buildings is most often wood. Sometimes, if there is such a possibility, they are done on those sides that are not adjacent to the house. We invite you to look at a few photos of wooden verandas attached to the house:

Looking at these photos wooden verandas, attached to the house, it seems that they were built by professionals, but this is not so. Today we will definitely look at how you can do this with your own hands.

Options for terraces attached to the house - how they differ from a veranda

We should start with the fact that many people confuse. But the differences here are fundamental. The fact is that the veranda is always attached to the house, but the terrace opposite is located and is not adjacent to the house. In addition, terraces are often without roofs and walls. At their core, they represent open . Hence the consequence - they are built more often from more durable material, which tolerates precipitation.

Of course, there are options for adding terraces to wooden ones, but this is rather the exception. Moreover, if we go back just a few decades ago, then at that time a terrace was considered to be an open (without roof) area of ​​natural or artificial origin.

Now many people confuse these two concepts, calling verandas adjacent to the house terraces on stilts, but still, historically this is not true. Although time does not stand still, a person tries to make his life more comfortable. This is probably why the area with a roof adjacent to the house was called a terrace. After all, it stands on stilts, while the veranda must have a foundation.

Here are some examples of terraces in photo illustrations:

How to attach a garage to a house and why it is needed

An extension to a house is quite good decision. Indeed, in this case, in the cold season there will be no need to go out into the cold to reach it. However, there are pitfalls here too. In the garage you need an ideal one that will not allow carbon monoxide enter the home. And no one doubts that the car will start in the garage for sure. Here are some photos of garages attached to the house:

Adding a garage to your home is not an easy task, but it is quite doable. You just need to understand how capital it will be. Will a foundation be needed, what will the floor and walls be like? The most common material for such buildings is foam block. But many, as a garage attached to the house, use several racks made of timber, on which it rests. Thus, although the car is not protected from snow and rain in the wind, the roof will protect it from the sun.

Examples of residential extensions to a wooden house

An extension to a wooden house as a living space or - this is perhaps the most common type of all listed. This is not surprising, because not everyone has the opportunity to buy land and build a new, large and spacious one. And the construction of an additional room is possible even at a relatively small area. But here the situation is a little more complicated than with the construction of a veranda or carport. Do not forget that the building must not only be capital, but also be sufficient so that one can live in it comfortably.

Important! When constructing such an extension, it is necessary to carefully study the soil, calculate a foundation that can support the weight of the structure, and also draw up a detailed project. Do not forget that such a capital structure must be registered with the cadastral chamber. Otherwise, you can not only lose money on fines, but also receive a notice of demolition of an illegal building.

Still, extensions to a country house are a good solution. After all, no one bothers you to collect all the necessary papers on time. And additional living space never bothered anyone. Moreover, it will not require too much money.

Extension to a wooden house: projects, materials and photos of possible layouts

Although it is difficult to make an extension to the house with your own hands, it is quite possible. But this will require some knowledge. The main thing that needs to be decided before undertaking such work is what material the structure will be made of. The following materials can be used:

• Boards on a timber frame. Such a building requires a minimal foundation;
• Rounded timber or logs– such a building also does not require too strong a foundation. The fact is that its lower crown will already play the role of support. In addition, such a structure will be warmer and more durable, but at the same time more expensive;
• . This is where you will need a very strong foundation that can support the weight of the building. Otherwise, the extension will begin to collapse in a year or two, and may not last even 3 months. It all depends on the soil;
• - he also demands solid foundation, perhaps even stronger than for a foam block. As a result, such extensions are very expensive.

Important! Regardless of what material it is decided to build a residential extension at the dacha, it must be firmly fixed to the house itself. Otherwise, the building will not have the required strength. In this case, there is a risk of collapse, and this is already life-threatening.

Let's try to understand each of these materials.

Extension to a frame house: nuances of construction, design and photo examples

An extension to the house is convenient because it requires the least cost and is easy to do with your own hands. Moreover, there is no need to work with a large number of people - two people are enough. But a foundation is still needed.

It is also convenient to make a frame extension to the house because there is no need to hire a designer who would calculate everything. This is another budget saving item. Of course, the extension will need to be insulated very well, but with the huge assortment on the shelves these days, this will be quite easy to do.

The most difficult stage in such construction will be the installation of the foundation. Well, assembling the frame, fixing it to the wall of the house and sheathing it is much easier. Today there are more simple ways. There is special material on sale. It's oriented particle boards. Moreover, with their help, the so-called one is manufactured at the factory, two sides of which are made of OSB, and between them a layer of foam plastic. This material is quite durable and strong, in addition, it has another important advantage- This is an excellent insulation material. Thus, the home craftsman can only assemble a durable frame and cover it with similar material.

External finishing is also important in such cases, because the durability of the frame extension to a wooden house largely depends on it. You can read about similar work in our other articles. And now we invite our dear reader to look at several photo examples of similar extensions made by home craftsmen:

Extension to a house made of timber - some installation nuances

When planning an extension, you should understand that both its foundation and service life depend on how it is designed. After all, no one will start construction with the expectation that in a couple of years living room will need to be demolished. Also, don’t think that you don’t have to “bother” with the design of such buildings. This is not a barn or closet, which means everything should be taken care of in advance.

Let's start with the fact that the best option (of course with low weight) would be a pile-screw. This will be a cheaper and less labor-intensive choice. Yes, and you can drive piles into the ground to the required depth yourself using special equipment or even manually. The main task here is to calculate the load on each pile to select their number and diameter.

Important information! When installing pile-screw foundation it should be understood that the supports must go under each wall. If there is a partition in the room, then they are also required under it.

You should also pay attention to the lower crown. It needs to be made from something more durable. Ideally, it will be made of logs. You should not think that to install a timber extension to log house only 3 walls are needed - this is a misconception. 4 walls are also being built, because a joint one is necessary here. It makes sense to pay special attention to the fastening between common walls. It depends on this whether cracks will appear in this place over time.

Here are some photo examples similar decisions:

Extension to a house made of foam blocks - advantages and disadvantages

This is probably the most common option. After all, foam block has a relatively low cost, can provide fairly good insulation (compared to brick), and the installation speed is considerable. But when compared with timber, foam block has a big drawback - it requires a fairly strong foundation. And you can’t get by with pile-screws.

A foundation for a foam block extension to a wooden house is required. The best option there will be a grillage pile foundation. This means that the cost of the foundation automatically increases significantly.

Installation of extensions to houses made of gas silicate blocks is also quite common. But some home craftsmen do not understand the difference between them and foam blocks. It's quite simple. a little heavier and more expensive than foam concrete, but at the same time its strength is much higher. In addition, it does not require coupling from concrete mortar(special glue is used). As a result, there are virtually no seams, which contributes to greater thermal insulation, and therefore lower heating costs in the future.

Important! Regardless of what building material is chosen, you should consider the communication systems in the future living room. After all, if this is not done, you will have to drill holes for heating and trench walls for electrical wiring. Without this, there can be no talk of any kind of living, much less a comfortable one.

We offer our dear reader several examples of such buildings:

Extension to a brick house - differences from previous options

The main difference here is that there is no fourth wall required. This means that three general ones are quite enough. The foundation can be either strip or columnar. And you can choose any material for construction - it all depends on the wishes and capabilities of the home craftsman.

Adhesion to the load-bearing wall of the house occurs using. When building an extension to a house made of brick or concrete, a reinforcement coupler is also often used. The load-bearing wall is drilled using a hammer drill, and the drill should be slightly smaller in diameter than the rod for a more rigid coupling. After this, a piece of reinforcement (it should not be smooth) is driven halfway into the drilled hole, and the second part is laid into the joint of foam blocks or bricks.

Important information! You should not start construction if the house is quite old. This is irrational, because the brick softens over time, which will have a bad effect on the adhesion to the new building. In addition, drilling the wall, as well as new construction, places additional stress on it.

Perhaps the dear reader will be interested in looking at some solutions of home craftsmen:

Construction of a foundation for an extension to a house and its types

The foundation is the foundation that supports the entire structure. This means that you should treat its design with great responsibility. The simplest solution for a light-weight building would be to install a pile-screw foundation. To do this, piles are screwed into the ground at a certain distance from each other, which will bear the main load.

If the building is heavier, you will have to pour a strip foundation. In this case, piles will also not hurt, they will provide additional strength. But the strongest of all types of foundations can be called a pile-grillage foundation. To install it, you need to dig a trench around the perimeter of the future walls. Afterwards, screw piles are driven along this trench or holes are drilled into which the reinforcement cage is lowered and filled with concrete. This is done in such a way that they top edge was slightly above ground level. And the last stage is to install the formwork and fill it with concrete. More details about how to make a foundation for an extension to a house or for a bathhouse are described in one of our articles.

Before pouring the foundation for an extension to the house, you should decide whether the ready-made solution will be ordered and delivered to finished form or make it yourself. In the latter case, accurate calculations of the components for the required strength are required.

How to make a roof for an extension

Most simple option there will be a device pitched roof for an extension to the house. This option is easy to implement and requires the least cost. However, such work also has its own nuances. If we compare it with gable roofs, then simpler ones do not retain heat so well.

When constructing a veranda, the three-slope option is often used for an extension to a house, but such work is quite complicated. If you have some skills and knowledge of carpentry, then a home craftsman will be quite capable of it.

Important! The roof should be designed so that snow can easily roll off it, but at the same time, safety should not be forgotten. After all, an accumulated snowdrift can fall on a person. That is why they try to make the slope steeper. In this case, the accumulation of snow will be small, and its removal will not be dangerous.

If House master I’m not sure that he knows how to make a roof on an extension to a house and will be able to do it, it’s better to seek help from specialists.

Instructions for installing a house extension with your own hands

Let's try to explain in general terms all the stages of constructing a veranda on a site adjacent to the house. More detailed instructions We will look at each type of building in the following reviews. Here's how to add an extension to your house:

Illustration	Actions Performed
	First of all, we start with the foundation. In our case, this is a well. Lowered into it metal pipe which is filled with concrete. Depth is about 1.7 m.
	The distance between the piles needs to be calculated. In our case, the weight of the veranda will be quite small, and therefore the distance can be made larger.
	We assemble a frame from the piles metal beams, which will play the role of the first crown, taking on the main load.
	The channels are welded together. In this case, the seam must be very strong.
	We also took care of communications. The water drain from the sink in the house ended up in this exact spot. Well, let's deal with this too.
	The holes in the channel are necessary for fastening the timber on which the entire structure will be built.
	We lay the timber around the perimeter and fasten it. You can begin building the main supports and roof.
	Having assembled the main frame from timber, we strengthen it with transverse beams. In their role we have, 50 mm thick.
	We place the boards supporting the roof in pairs and tighten them together.
	It should look something like this. It should be noted that the boards that support the roof also give strength to the frame. They are secured to the main beams using tie rods.
	The roof can be covered with corrugated sheeting. It is quite resistant to any weather conditions.
	The diagonal board plays a rather important role - it prevents the building from tilting due to the supporting beam of the frame. In our case, ordinary railings were made, but it is fashionable to sheathe or deglaze the building.
	Here the diagonals are decorative, and therefore made of thinner boards.

In general terms, the answer to the question of how to add an extension to a house looks like this.

The cost of specialist services for such construction

It is unlikely that you will be able to build an extension to your house inexpensively if you turn to specialists. But for general information It wouldn’t hurt to consider the prices for such services using the example of various verandas:

Photos of verandas and terraces attached to the house: the work of professionals and not only

For those who still doubt that without special knowledge and skills it is possible to make a rather beautiful extension to the house - photo examples of verandas and terraces made by ordinary home craftsmen. Perhaps the dear reader will find some solutions for his work. If not, then you can just admire it. It's really beautiful.

Surely many people liked the photos of verandas attached to the house with their own hands.

Finally

It is unlikely that anyone can refuse an additional room attached to the house. But it’s one thing when this work was done by strangers, and completely different if everything was done with your own hands. Moreover, as it turned out, although this is difficult, it is quite doable. Is it then worth paying money to “someone else’s uncle”? And it’s not a fact that the construction will turn out to be of high quality and beautiful (there are plenty of hacks these days). To the veranda mentioned in step by step instructions, including painting it took about 10 days. This means that in a maximum of 15-20 you can make it completely perfect. Experts promise to do all the work in 30-60. It's worth thinking...

We hope that the information we presented today was useful to the reader. All questions (if you still have them) can be asked in the discussions for the article. Write, share your experience, because it may help someone.

Extension to a wooden house

A house made of wood is a special home that is preferred by people who value practicality, functionality and the opportunity to live in an environmentally friendly home. In addition, a wooden house is also more economical: starting from the fact that the construction does not require a very strong foundation and ending with the fact that the heating costs of such housing are much lower than concrete ones.

But what to do if the house has already been built, but any wishes of its owners are not taken into account or there is simply not enough space. The way out of the situation would be to build an extension to a wooden house. Depending on the needs of the owners of the house, it is possible to complete not only a veranda or a kitchen, but also a bathroom or a full-fledged living room - a living room or a bedroom. The principle of construction of any of these premises will be similar, but it is worth assessing the condition of the house and its load-bearing wall. When designing an extension, it is important to consider how it will fit into the design and architecture of the house.

Premises requirements

When planning an extension, it is worth considering in advance the purpose of the future premises and the features of its operation.

If you are planning to add a bedroom or living room, then the room should have:

• reliable foundation;

• good waterproofing.

Compliance with these requirements will make it possible to connect the premises to heating system home and ensure a comfortable temperature in it.

If you plan to build a kitchen or bathroom, then before building the foundation you need to take care of the connections: water and gas supply, sewerage. Insulation of walls, ceilings and floors, as well as waterproofing are no less important points.

For the construction of a veranda or open terrace no communications required. A solid foundation with waterproofing will be enough to prevent moisture from penetrating into the room.

When installing a boiler room, the annex must be connected to the sewerage system, have a sufficient area (at least 15 cubic meters), as well as reliable ventilation system. Free access to the heating unit is an important safety requirement. The boiler room cannot be attached to a wooden house in a place where there are doors or windows - only blank walls can be used.

If you are planning to add a garage, you need to provide exhaust ventilation(natural or forced). This will protect your home from exhaust gases from the garage, as well as from other unpleasant odors. In addition, the garage must be provided with a water supply and drainage system, electrical wiring, fire alarm and heating (if year-round living is expected).

A porch is another option for an extension. May have several steps, be built from wood or blocks, and must be equipped with railings for safety.

According to the law, before constructing an extension, you must obtain permission from the appropriate authority, so that you do not have to demolish it later.

Construction of the foundation for the extension

A solid foundation is the key to strength, as attached structure, and the house itself. There are three types of foundations:

• tape;

• monolithic;

• columnar.

The right decision when choosing the type of foundation will be the same as that under the house itself.

It is important to think in advance about how the two foundations will be connected. As a rule, in old design the fittings are clogged, which are then installed in a new one. This method guarantees strength and prevents the building from settling. The doorway can be cut down in the place where the window is structurally provided.

A strip foundation is a strip of reinforced concrete running along the perimeter of the entire building. The depth of such a foundation should be less than the depth of soil freezing. Due to the shallow depth, sufficient reinforcement of the structure must be provided so that the expanding soil does not destroy it. If executed correctly, the strip foundation of the house will be durable and relatively inexpensive; it will be suitable for lightweight structures.

Monolithic foundation - suitable for those regions where the soil freezes to a great depth. During its construction, you need to mark the site, dig a pit, lay out its bottom sand cushion. A mandatory step is installation drainage pipes and waterproofing of formwork. Construction of a monolithic foundation is a complex and expensive process, but such a structure will serve for many years.

Columnar foundation - its principle is based on the fact that pillars are erected at all points of intersection of the walls. This type of base is suitable for lightweight structures and is the most inexpensive. The advantage of the columnar type is that it can withstand the effects of unstable soil and does not require waterproofing. However, you should take a responsible approach to floor insulation.

Installation of the base floor of the extension

The floor in the extension can be concrete or wood. Each of the materials has its own advantages.

• cannot be laid on a columnar foundation;

• poured after installation of formwork and reinforcement of the structure;

• requires additional thermal insulation so as not to heat the surrounding area;

• has high strength, long term service, not exposed to dampness, fire and fungi.

• has high heat and sound insulation properties;

• lightweight, does not affect the foundation;

• can be quickly installed and used immediately after installation;

• environmentally friendly;

• susceptible to the destructive effects of humidity, afraid of insect pests, open fire and mold.

Despite the disadvantages of wood, own home nevertheless, it is preferable to use it. If the wood is well protected, first with an antiseptic, then with varnish or paint, then such floors will last for many years.

The option of constructing a wooden floor on joists is used. The essence of the design is that the floor level rises by required height, the basement space is filled with soil. Wooden blocks are laid on special posts, and floor boards are placed on top of them.

To ensure comfortable living in the extension, it is necessary to take care of the insulation of the subfloor and its ventilation.

Construction of extension walls

When building walls, you need to consider the following rules:

• the height of the extension wall should be slightly lower than the wall of the house;

• it is advisable to use elastic connection of structures;

• the extension wall should not fit tightly to the main wall.

When choosing a material, it is important to take into account construction technology, the purpose of the building and the budget. It is necessary to take into account that the structure must have a holistic appearance with the house.

Depending on the design of the house, you need to build two or three walls.

If you plan to build an extension from timber, then the presence of a foundation is a prerequisite. The timber can be rounded, planed or glued. If the last one has the best thermal insulation properties, then the first is an attractive appearance. It must be taken into account that this is a fairly heavy material, so the structure will shrink over time.

Advantages of timber:

• low cost;

• environmental friendliness;

• construction will not take much time.

The upper part of the building should be provided with piping made of the same material.

Advice from experienced builders when building an extension from timber:

• to reduce the shrinkage period it is better to perform construction works in the cold season;

• It is better to perform thermal insulation of timber with inside, and leave the outer part attractive;

• fireproof and antiseptic treatment are steps that cannot be neglected;

• choose fastening materials made of galvanized metal and, if possible, reduce the number of such elements.

You can make a wooden extension from timber to brick house. In this case, docking with the main object requires the use of movable type seals. This will help avoid drafts and heat loss.

If the extension to a wooden house is made of concrete blocks, then for joining it is necessary to perform gating with laying of reinforcement. When performing masonry, tying and precise placement of corners is required.

Brick is a strong and durable material; in combination with double-glazed windows, such an extension will become reliable and functional. The material is quite heavy, so a reliable foundation is important. Key points:

• wooden structure must be good quality, without areas of rot and decay;

• the foundation should be strip, or better yet monolithic;

• Brick laying must be done from the wood side in compliance with technological gaps;

• U-shaped channels are used to connect buildings.

Cinder block is an affordable material that can provide high level thermal insulation due to a special porous structure. And due to the fact that the blocks are large, the construction period is reduced. In addition, the extension will not be heavy, which means it does not require a reinforced foundation.

An extension to a wooden house made of foam blocks will have the following advantages:

• environmental friendliness;

• low fire hazard;

• high heat and sound insulation;

• cost-effectiveness and ease of construction;

• reliability and long service life.

The disadvantages of cellular concrete blocks include high hygroscopicity and unpresentable appearance. But these visual defects can be easily eliminated by installing waterproofing protection and finishing the facade with decorative materials.

The aerated concrete extension has the same features as the previous version. All the risks of such structures are associated with the fact that dissimilar materials can move differently relative to each other under the influence of unfavorable factors. Experts do not recommend attaching the extension to the wall of the house - it is erected in the immediate vicinity and the joints are insulated.

The construction of an extension to a wooden house made of gas silicate blocks can begin immediately after the foundation hardens. It needs to be lined with roofing felt and used cement-sand mortar for the first row. Laying blocks starts from the corner. All subsequent rows are interlocked with each other using a special adhesive composition.

The SIP panel consists of two OSB boards, between which there is insulation - polystyrene foam or polyurethane foam. This material has low weight, affordable cost and high strength. An extension made from SIP panels will be rational solution for people with a small budget, and the construction of even the largest objects will take no more than 2 weeks. Such an extension will be warm, light and inexpensive. The work can be carried out at any time of the year and does not require a large number of workers.

Extension ceiling and roofing

When covering the roof in an extension, you need to make sure that it goes under eaves overhang home, and the resulting transition was smooth. It is important to ensure such a connection is made to minimize the possibility of moisture getting underneath it.

It is advisable to make the transition from galvanized steel, bringing it 30-40 cm under the roof of the house and leaving it on the surface of the extension roof for the same amount. All voids and gaps must be treated with sealant.

Sequencing:

• construction of a rafter system;

• creating sheathing or flooring;

• facing of gables;

• covering cornices;

• installation of wind parts;

• roof installation.

Roof beams can be made from wooden beam, laid in grooves prepared in advance. The roofing material must be identical to the roof of the house.

To insulate the ceiling you can use: mineral wool, expanded clay.

For internal insulation extensions, you can use plasterboard - this inexpensive material, which is easy to work with. In a heated room, work can be carried out regardless of the time of year:

• First, the profile is drilled;

• plasterboard, cut into pieces of the required size, is mounted to the profile;

• A layer of insulation (Isover) is laid between the wall and the drywall.

Thanks to such simple actions, a thermos effect is created in the room.

Save money without harming quality, requirements for premises and materials

If during the construction of an extension there is a question of saving, then it makes sense to give preference frame method. Its advantages:

• affordable price;

• possibility of construction in a short time;

• it is easy to attach to the main structure.

A frame extension is built from beams or planed timber. The assembled frame is sheathed with pressed wood and additionally insulated.

If you take a responsible approach to heat and waterproofing, the extension will be comfortable to live in.

To connect to the house, you will need to connect the walls with powerful screws and seal the joints.

Selecting a construction team and the secrets of strict control

When choosing a team of workers to build an extension, it is important to immediately clarify the timing, cost and quality of the work. It is better to use the recommendations of friends and see with your own eyes the result of the work of this team. It is important to draw up an estimate and approve it, establish stage-by-stage payments, and not pay an advance (or give the minimum).

To control the work, you can hire an independent foreman, carry out unexpected checks yourself, and pay for the work only after drawing up a handover certificate.

1 How to quickly and cheaply make a foundation for a house or extension

2 Choice construction crew and the secrets of strict control

Over time, almost every owner of a private home has a desire to enlarge their country house. And an excellent solution in this matter would be an extension to an existing house.

Construction work begins with drawing up a project, where it is necessary to clearly and clearly draw a plan of the planned object, think through the connection of all premises with the existing house, choose the type of structures, foundation and decide which ones Construction Materials will be used. The financial costs of construction will depend on the correct development of the design stage. At this stage, it is also worth deciding on the nature of the use of this building, namely, whether it will be seasonal or year-round, and also decide how many storeys the new building will have.

There are several common types of extensions that can be classified according to their purpose.

Summer room (kitchen or veranda).

Such an extension is usually one-story and is used in the warm season. It is convenient for spending time together, family dinners, relaxation, etc. Of course, it is necessary to construct a light or shallow foundation, preferably independent from the main building of the house.

Such a structure usually has pitched roof(Fig. 1, 2). It is recommended to use metal tiles or polycarbonate as roofing materials. In this case, it makes no sense to do thermal insulation, because the room will not be used in winter. It is worth noting that minimum angle the roof slope is 8°, you cannot do less, otherwise leaks will appear after rain and snowfalls.

Living room and attic, if the extension is two-story (Fig. 3, 4).

In this case, a more thorough approach will be required for the construction of the foundation, construction main walls and roofs, as well as installation of waterproofing and thermal insulation materials, supply of all utilities.

Should be given Special attention thermal insulation of walls, roof and floor, taking into account that the extension will be used in the cold season, and accordingly heating.

Before starting construction, you need to consider the condition of the house. The pairing of roofing and foundation structures will depend on this criterion. And it is worth considering that due to the difference in the magnitude of the load that the main structure and the extension will exert on the ground, there is a high probability that over time they will move relative to each other.

Another option for an extension to the house could be a separate building, closely adjacent to the main one., which quite often becomes the only possible

because of an old house may not withstand the reconstruction of the roof, and this will compromise the stability of the entire structure.

Also the extension may differ in the type of foundation. Usually, a separate foundation is arranged for an extension, which is connected to the base of the old house using embedded reinforcement.

Of course more correct option- This is the general foundation that is laid at the stage of building a house. However, this happens quite rarely, and therefore it is worth ensuring maximum similarity of the foundations in terms of material and depth.

The most constructive and competent solution may be a separate foundation for the extension. The most common foundation in this regard today is a foundation on screw piles (Fig. 5, 6). After screwing into the ground, the piles are combined into a single grillage by welding several metal channels or wooden beams. This results in a separate and independent foundation, which will not be connected in any way to the main house, since existing foundation may continue its downward movement, which can lead to deformation of the structure.

At the same time, between two buildings a minimum of possible distance, i.e. a technological gap that is filled with thermal insulation and waterproofing materials.

An extension to the house can be made according to frame technology or from a wooden beam (Fig. 5, 6).

Frame technology the most acceptable, since it is light in weight and consists of the construction of a frame made of wooden beams and filled with insulation. For example, these can be SIP panels, which in cross-section represent a three-layer “pie” of two load-bearing surfaces (usually OSB), between which foamed polystyrene foam is pressed, where the thickness of the insulation can be different, so you can select panels for any climatic region. In this case, there will be no need for cladding with additional materials, which will reduce the cost of construction.

It will be enough to paint the interior panels with varnish. It is also worth saying that a timber extension to a wooden house can be of two types: three walls and a fourth load-bearing one, which is already in the house, or three walls, which is the most reasonable in terms of material consumption. If planned winter accommodation, then it is worth using a material whose cross-section is at least 150 x 150 or 200 x 200 mm.

This beam is quite heavy, but it will also last longer. After the walls are erected, the remaining cracks must be sealed, otherwise it will be very cold in the extension. This can be done using modern insulation based on basalt wool or polyurethane foam.

For for sheathing an extension to a frame house, any materials are suitable. These can be boards, OSB (oriented strand board), siding, blockhouse, etc. Material exterior finishing depends on the financial capabilities of the owner.
