How to place an extension to the house. How to attach a veranda to a country house: first-hand step-by-step instructions

One of the advantages of private households is the ability, if necessary, to increase the usable area by adding an additional one to the main structure. Thus, residential or utility rooms are obtained, for whom what functionality was not enough. In order for the extension to improve the living conditions of the owners, and not organize problems for them, it must be built according to existing technologies, and not according to the principle "somehow, if only it would be cheaper." Therefore, we will figure out how to properly settle down to the house, based on generally accepted methods and experience of FORUMHOUSE users.

Foundation for extensions

There are two types of foundation for an extension - a rigid hitch and expansion joint.

rigid hitch
Such a connection is designed for non-rocky soil and is justified when erecting a heavy structure of two or more floors, but only if the main building has already settled down and the village. The new foundation must be of the same type as the main one (tape, slab) and match in depth, taking into account possible shrinkage. A bunch of tapes is made by means of reinforcement, for which the foundation of the house is dug out to the full depth; in the working area, too much exposure is fraught with deformation.

Holes for reinforcement are drilled in a checkerboard pattern in the foundation web, on the basis that their length is 35 times the diameter of the rod, and the length of the reinforcement itself is twice as large as the depth of the holes. The reinforcement is driven into the holes, in the future the protruding part will be filled with concrete, a common monolith will be obtained. A bunch of plates is possible with a thickness of more than 40 cm and the presence of a protrusion of the main plate of 30 cm; for coupling, the reinforcement is beaten off and welded to the reinforcing cage of the new plate.

To perform a rigid hitch, it must be borne in mind that the flooded one, connected to the main one, must settle, ideally within a year. If it is not possible to withstand such a period, it is better to use another method.

Expansion joint
The most common type of bond is when a completely independent one is poured near the old foundation. Optimal for heaving soils for lightweight structures, the thickness of the seam is from 2 to 5 cm. In order to aesthetically connect the foundations, and
the seam at the junction remained the same along the entire length; boards pre-wrapped with polyethylene or roofing felt are used. Since the load on the base will be less, the drawdown will also be less, and the seam will allow the extension to “play” as planned without affecting the integrity of the house.

During the construction process, the joint between the walls is filled with insulation, and the seam itself is subsequently sealed with elastic means or closed with special flashings. One of the users found an interesting solution - stainless steel overlays, between which there is a layer of corrugated rubber.

In principle, you can buy such a “closing” for an expansion joint, immediately insulate the distance between the walls normally, close it from the street with a “closing”, and if over time there is shrinkage, compression or stretching, the “closing” compensates for this moment. And in order to return the rubber to its previous shape, it will be possible to unscrew the screws from the left side and drill again, in new places in the bricks.

Since the foundations are not interconnected, any type can be chosen for the extension, based on the characteristics of the soil and the expected load. It can be slab (monolith or UWB), tape (MZF or to the freezing depth) or columnar (pile).

Portal users prefer joining foundations through expansion joints, as the most justified and safe way.

Whatever good (non-rocky) soil, if it is not a rock, then you should expect shrinkage of the foundation of the extension in relation to the main house. Accordingly, measures must be taken to ensure that these shrinkages are non-destructive to the structure and provide acceptable functional properties of the structure. Hence: annex - in fact new house next to the old or light structure, the walking of which is permissible, and violations of the horizontal floor and jamming of the doors are permissible.

materials

The modern building materials market offers a wide choice for every taste and budget. Extensions made of foam concrete, aerated concrete, cinder block and similar large-format masonry varieties and frame structures are most in demand today. Frames are in the lead due to the speed of construction, relative accessibility and simplicity; in terms of energy efficiency, they are not inferior to stone buildings due to the use of heaters.

However, if possible, it is recommended to choose a material similar to the main one: a wooden extension to wooden house etc. This is especially true for houses that are not supposed to be sewn up with the same facade as the extension. If you plan to use siding or similar cladding, the choice is not limited.

Wall tie options

An extension to the house can have four walls or three, then the role of the fourth plays outer wall Houses. Four walls are relevant in extensions from masonry materials, a bunch of walls is not required, and compliance with the masonry level gives an even seam. The presence of a layer of insulation between the walls allows the use of thinner blocks for the adjoining wall. At frame construction sliding ligaments are used: two vertical beams are stuffed onto the wall, between which a vertical extension beam is inserted.

Connecting beams in the annex

When the extension is assembled from profiled or glued beams or logs, the walls are connected to the house either with metal brackets or with special galvanized corners with a shelf of 63 mm or more.
The corners are planted on self-tapping screws, leaving a small gap for shrinkage. The seam in both cases is closed with a flashing or platband. Also, the joining of the beams in the extension is carried out by means of a tenon-groove system, the grooves are selected in the load-bearing wall, the tenon is cut on the built-in segments.

Roof device methods

The extension is brought under a common roof, when a rigid connection is made, if an expansion joint is selected, it is easier to cover the building separately, sealing the junction. Depending on the roofing material, the seam is closed with a stainless steel apron, 30 cm wide or with a special decorative element.

Rigid connection to the house from a bar.

mfcn

The shrinkage of the extension in relation to the main house imposes certain restrictions on the arrangement of the roof. Therefore, in practice, making an extension with a roof such as a continuation of the existing one should be deliberate and reasonable.

Functional

As with the construction of a house, before erecting an extension, it is necessary to determine in advance the functionality, since different purposes require appropriate construction manipulations. If it is supposed to make living rooms, enhanced insulation is necessary. For the boiler room, bathroom or kitchen, communications are immediately laid. It's easier to change your mind and close a couple plastic pipes into the wall than to decide that another bathroom is more needed and peck at a freshly built one.

Legalization of the extension

Before building a major extension, a permit must be obtained. In the city, this is done by the department of architecture and urban planning, in rural settlements - by the administration. You can build without papers, but then when you try to sell, bequeath or donate a house with an extension, you still have to draw up documents, but it’s more difficult, through the courts. In the event of a confrontation with the neighbors, they can sue the self-builder and insist on the demolition.

For anyone planning an extension, it is useful to study the topic on the forum. The user experience of our portal in the topic is also interesting. The article will help determine the type of foundation for the future design. And our video will teach you how to work with aerated concrete.

many owners country houses and dachas from time to time carry out redevelopment of plots with their own hands. But sometimes you have to touch the house. If it needs expansion, then the extension - perfect option increase usable area. At the same time, it can perform completely different functions and be located not only at the main entrance. Projects of extensions are developed taking into account the peculiarities of their operation.

Types of buildings

Before choosing an extension project with your own hands, you should decide on its functional purpose. Typically, the following types of buildings are attached to the house:

For each type of extension, it is necessary to calculate the amount of materials and draw up a plan.

Types of structures of residential extensions

There are several basic options for do-it-yourself extensions to the house:

The first option is considered not only the easiest from a technical point of view, but also the most budgetary. He assumes that the roof of the main building remains in place, only slightly lengthening by the size of the extension to the house. The main building is completed on one side or two. Then a passage is punched between them so that the total area of \u200b\u200bthe building increases by the size of the new building.

An attic-type room will be more expensive, as it is supposed to carry out an add-on.

The third option for an extension to the house with your own hands involves your own roof. The rest of the structure resembles a side structure. A separate roof increases the consumption of material, so the extension will cost more and will be built a little longer.

The extension of the second floor is carried out only if the foundation of the house allows it. If initially the building was not planned to be multi-storey, then there may be problems with its completion. The foundation may simply not withstand the additional load. In some cases, it can be strengthened.

Designing a new premises

According to the law, any functional room is considered an extension to the house with your own hands. A balcony, a loggia, a winter garden or an additional bedroom - all this will be considered an extension. Mandatory elements her designs are:

foundation;
walls.

Unlike the main building, there may not be floors here. Constructive decisions for the roof of an extension with your own hands the following:

The foundation of the building is recommended to be erected separately, since the structures are operated under various loads.
At the design stage, it is very important to consider the compatibility of the new building with the old one. An extension with your own hands should not create obstacles to communications that pass through the site. If you plan to make multi-level buildings, then you need to consider that this will delay the snow masses. Therefore, they should be further strengthened to avoid subsidence of the foundation.

Foundation design

With an increase in the usable area of an existing building in the horizontal direction, it is unprofitable to build a slab or strip buried foundation. The most economical base designs are:

If preference is given to a pile or column foundation, then it is necessary to perform additional protection of the lower part of the structure from freezing. For this purpose, you can use basement siding with an inner layer of insulation in the form of basalt wool or expanded polystyrene.

Wall design

When drafting an extension, you should decide in advance on the material for the walls. For frame or panel construction, a sandwich is used:

OSB sheets with a layer of expanded polystyrene or stone wool;
internal membrane for vapor barrier;
outer film for waterproofing.

The laying of lightweight blocks - aerated concrete or foam blocks - will cost a little more. If preference is given to the latter, then it should be taken into account that even walls made of the highest quality foam concrete are often covered with a network of cracks. Therefore, the facade will need to be plastered on a reinforcing mesh special composition.

Roof design

When designing an extension to a house with your own hands, you need to calculate the reliability of the elements of the truss system, their configuration and choose a step for their placement. If the height of the walls is the same, then the supports can be based on the existing load-bearing structures. The rafters of the lower extension to the two-story building should rest on the columns located near the walls of the main building.

Most often, the slope of the roof of the house closest to the extension is dismantled. The elements of the truss system are replaced by new ones that have a greater length.

Alternatively, you can disassemble the roofing cake, but do not dismantle the rafters. For a new building, a shed roof is being erected. Enhance truss system can be racks.

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

On the Internet you can find various projects outbuildings 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 building that will not only be, but also increase your living space.

Many may say that such construction is too labor-intensive and almost impossible to do on their own, but this is a delusion. With the right approach and the study of all the nuances, this is not so difficult, although you will have to face some difficulties. But, as they say, the eyes are afraid, but the hands are doing. But as a reward, you can get not only a do-it-yourself extension to a wooden house, but also satisfaction from the work done. In addition, the funds saved on the remuneration of specialists will not be superfluous.

Consider various options outbuildings in in general terms, as well as examples of similar works done by ordinary home craftsmen without any experience.

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

Such a building is quite relevant for summer residents who love to sit in the evenings over a cup of tea with family or friends. After all, on fresh air much nicer to talk to than indoors. In addition, it is possible that the veranda will be thought out in such a way that it is possible to install. This will protect it from snow, as well as add warmth to the house itself.

Another plus of such a building is that on winter period you can go there. 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 indoors for a whole year.

The material for such buildings is most often wood. Sometimes, if there is such an opportunity, it is made on those sides that do not adjoin the house. We offer you to see a few photos of wooden verandas attached to the house:

Looking at these photos of wooden porches attached to the house, it seems that they are built by professionals, but they are not. Today we will definitely consider how you can do this with your own hands.

Variants of terraces attached to the house - how do they differ from the veranda

You should start with what many 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 does not adjoin the house. In addition, terraces are often without a roof and walls. At their core, they are open. Hence the consequence - they are built more often from a more durable material that tolerates precipitation.

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

Now many people confuse these two concepts, calling verandas adjacent to the house as terraces on stilts, but this is still not true historically. Although time does not stand still, a person is trying to make his life more comfortable. This is probably why they called the terrace a platform with a roof adjacent to the house. 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 the house and what is it for

Adding to the house is very 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, even here there are pitfalls. The garage needs an ideal one that will not allow carbon monoxide enter the dwelling. And the fact that the car will start in the garage for sure, no one doubts. Here are some photos of garages attached to the house:

Adding a garage to the house is not an easy task, but it is quite feasible. It is only necessary to understand how capital it will be. Do I need a foundation, what will be the floor and walls. Most often, the material for such buildings is a foam block. But many, as a garage attached to the house, use several racks of timber, on which they rely. Thus, although the car is not protected from snow and rain in the wind, the roof will save it from the sun.

Examples of residential extensions to a wooden house

Attach 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, build a new large and spacious one. And the construction of an additional room is possible even on 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 should not only be capital, but also enough so that you can live in it comfortably.

Important! When erecting such an extension, it is necessary to carefully study the soil, calculate the foundation that can support the weight of the structure, and also draw up 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 notification about the demolition of an illegal building.

And yet, extensions to country house are a good solution. After all, no one bothers to collect all the necessary papers in time. And the extra living space has never bothered anyone. In addition, it does not require too much money.

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

Making an extension to the house with your own hands, although difficult, 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 material can be the following:

Boards on a frame made of timber. Such a building needs 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 a support. In addition, such a structure will be warmer and more durable, but at the same time more expensive;
. Here you 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 even stand for 3 months. It all depends on the soil;
- it also requires a 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 residential extension in the country, it is necessary to firmly fix it to the house itself. Otherwise, the building will not have the necessary strength. In this case, there is a risk of collapse, and this is already life-threatening.

Let's try to deal with each of these materials.

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

An extension to the house is convenient in that 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 still, a foundation is needed.

It is also convenient to make a frame extension to the house due to the lack of the need to hire a designer who would calculate everything. This is another budget savings item. Of course, the extension will need to be insulated very high quality, but with a huge assortment on the shelves these days, this will be quite easy to do.

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

Important in such cases exterior finish, 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 the dear reader to look at a few photo examples of such extensions made by home craftsmen:

An extension to a house made of timber - some installation nuances

When planning an extension, it should be understood 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, do not think that with the design of such buildings you can not "bother". This is not a barn or closet, which means that everything should be taken care of in advance.

Let's start with the fact that the best option (of course, with a small weight) would be a pile-screw. It will be a cheaper and not too labor intensive choice. Yes, and you can drive piles into the ground to the required depth yourself with the help of 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! On device pile screw foundation it should be understood that the supports must pass under each wall. If there is a partition in the room, then under it they are also required.

Attention should also be paid to lower crown. It must be made from a more durable one. Ideally, if it is from logs. Do not think that for the installation of an extension from a bar to log house only 3 walls are needed - this is a delusion. 4 walls are also being built, because a joint one is also needed 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 the house of foam blocks - advantages and disadvantages

This is probably the most common option. After all, the foam block has a relatively low cost, it can provide quite good insulation (in comparison with a brick), and the installation speed is considerable. But when compared with a bar, the foam block has a big drawback - it requires quite a strong foundation. And already pile-screws are indispensable here.

The foundation for an extension from a foam block to a wooden house is necessary. 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. Everything is pretty simple. slightly heavier and more expensive than foam concrete, but at the same time its strength is much higher. In addition, it does not require a hitch from a concrete solution (special glue is used). As a result, there are practically no seams, which contributes to greater thermal insulation, and therefore lower heating costs in the future.

Important! Whatever is chosen building material, you should consider communication systems in the future living room. After all, if this is not done, you will have to hammer holes for heating, ditch the walls for electrical wiring. Without this, there can be no talk of any living, especially comfortable.

We offer the dear reader a few examples of such buildings:

Extension to a brick house - differences from previous options

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

Grip with bearing wall at home happens with the help of . When building an extension to a house made of brick or concrete, a reinforcing hitch is also often used. Bearing wall drilled with a puncher, while the drill should be slightly smaller in diameter than the rod, for a more rigid hitch. After that, a piece of reinforcement (it should not be smooth) is driven into the drilled hole up to half, and its second part is laid into the joint of foam blocks or bricks.

Important information! You should not start building if the house is quite old. This is irrational, because the brick softens over time, which will have a bad effect on the coupling with the new structure. In addition, the drilling of the wall, as well as the new building, create an additional load on it.

It may be interesting for a respected reader to look at some of the solutions of home craftsmen:

The device of the foundation for an extension to the house and its types

The foundation is the foundation that holds the entire structure. So, you should treat his device with great responsibility. Most simple solution with a small weight of the building, there will be a pile-screw foundation. To do this, at a certain distance from each other, piles are screwed into the ground, which will carry the main load.

If the building is heavier, you will have to fill in the strip foundation. At the same time, piles also do not interfere, they will give additional strength. But the most durable of all types of foundations can be called a pile-grillage foundation. For its device, you need to dig a trench around the perimeter of future walls. After, they are already driving along this trench screw piles or they drill wells into which they lower reinforcing cage and filled with concrete. This is done in such a way that their upper edge is slightly above the ground level. And the last step is to install the formwork and pour concrete. For more information on how to make a foundation for an extension to a house or for a bath, see one of our articles.

Before you pour the foundation for an extension to the house, you should decide whether ready solution order and deliver ready-made or make your own. In the latter case, you need accurate calculations components for the necessary strength.

How to make a roof for an extension

Most simple option there will be a device pitched roof for an addition to the house. This option is easy to implement and requires the least cost. However, this work also has its own nuances. When compared with gable ones, the simpler ones do not retain heat so well.

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

Important! The roof should be thought out so that snow can easily roll off it, but do not forget about safety. After all, the accumulated snowdrift can fall on a person. That is why they try to make the slope more abruptly. In this case, the accumulation of snow will be small, and its removal is not dangerous.

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

Instructions for installing an extension to the house with your own hands

Let's try to explain in general terms all the stages of building a veranda on a site adjacent to the house. More detailed instructions for each type of buildings we will analyze in the following reviews. Here's how to make an extension to the house:

Illustration	Actions to take
	First of all, we start with the foundation. In our case, this is a well. dropped into it metal pipe which is filled with concrete. Depth of about 1.7 m.
	The distance between the piles must 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 of metal beams on the piles, which will play the role of the first crown, which takes on the main load.
	Channels are welded together. In this case, the seam must be very strong.
	We also took care of communications. Draining water from the sink in the house was in this place. Well, let's deal with that.
	The holes in the channel are necessary for fastening the timber on which the entire structure will be built.
	We lay the beam around the perimeter and fasten it. You can start building the main supports and the roof.
	Having assembled the main frame from the timber, we reinforce it with transverse beams. In their role we have, 50 mm thick.
	We put the boards supporting the roof in pairs and tighten them together.
	It should look something like this. It should be noted that the boards supporting the roof also give strength to the frame. They are fixed to the main beams just with the help of tie rods.
	The roof can be covered with corrugated board. It is quite resistant to all weather conditions.
	The diagonal board plays pretty important role- it does not allow the building to roll 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 attach an extension to the house looks like this.

The cost of services of specialists in such construction

It is unlikely that it will be possible to build an extension to the house inexpensively when contacting specialists. But for general information It does not hurt to consider the prices for such services using the example of various verandas:

Types of verandas	Cost of work, rub. for 1m 2
open annex	from 8 000
Frame extension with insulation 50mm	from 9 000
Frame extension with insulation 100mm	from 10 500
Frame extension with insulation 150mm	from 11 500
Extension from profiled timber 90x140mm	from 10 500
Extension from profiled timber 140x140mm	from 12 500

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, you can 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 enjoy. After all, it is really beautiful.

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

Finally

It is unlikely that anyone can refuse an extra room attached to the house. But it’s one thing when this work was done by strangers, but it’s completely different if everything is done by one’s own hands. In addition, as it turned out, although it is difficult, it is quite doable. Is it worth it then to pay money to "someone else's uncle"? And it’s not a fact that the building will turn out to be of high quality and beautiful (there are enough hacks in our time). On the veranda, which was mentioned in the step-by-step instructions, it took about 10 days, along with painting. This means that for a maximum of 15-20 you can make it completely perfect. Specialists promise to do all the work in 30-60. Worth thinking...

We hope that the information presented by us 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 can help someone.

Frame extension to a wooden house

When a frame extension to the house is being built, step-by-step instruction provides not only work on the preparation of estimates and the coordination of the project of the future structure. There are a number of nuances that need to be taken into account.

Do-it-yourself frame extension.

Before coordinating the project and building a frame extension, you need to choose what it will be and what goal is pursued by the new construction work:

The easiest in terms of implementation and cost of a do-it-yourself frame extension to a house is a summer veranda or a terrace for relaxing in the summer. Due to the seasonality of operation, the premises will not require large investments. Minus high-quality insulation, moisture-proof and heat-insulating membranes. You will also need to use high-quality tiles for the terrace when mounting summer kitchen. If the summer veranda is not used as a summer kitchen, then it will not be necessary to lay engineering communications at the initial stage of construction.
A frame extension to a wooden house can be an additional full-fledged living space in an existing dwelling - with one or more rooms. In this case, the design will require additional insulation to reduce the cost of heating the room, choosing a more solid type of foundation and carrying out moisture insulation work.
An extension to the old house of additional utility rooms, which will require timely and competent laying engineering communications at the construction stage. All pipes must be carefully insulated for their further year-round use.

On a note

The choice of the type of frame extension to the house is also important in order to ensure the best connection with the already built walls, foundation and roof of the old house. If you do not attach importance to the similarity of the structures of both buildings, there may be a skew or shrinkage of the house, cracks and further destruction of the structure.

Foundation selection

The type of foundation that builds to build also depends on the further intended use of the frame extension. Ideally, the foundation of the main part of the house should match the extension.

Pile foundation.

The choice of a foundation for a frame extension with your own hands depends largely not only on the characteristics of an already erected wooden house, but also on the natural conditions and the quality of the soil at the construction site. The main list of materials used is as follows:

Concrete.
Brick.
Stone.
Wooden beams and piles.
Metal rods.

On a note

When choosing the type of foundation, it is necessary to take into account the depth of the main structures. When erecting a multi-storey or massive extension, the depth must be made by more than 700 mm.

The main types of foundation that are selected when building a do-it-yourself frame extension are:

Tape.
Slab.
Pile.
Columnar.
Pile-grillage.

Strip foundation.

If the building is planned to be two-story or massive, it is necessary to make a choice in favor of a strip foundation. When using it during the construction of a do-it-yourself frame extension, the following step-by-step instructions:

It is necessary to mark the territory. This is done with the help of wooden pegs and a rope stretched between them. The marking will mark the place for the trench under the future strip foundation.
The soil is excavated according to the depth of the already established foundation for the house itself, or to the depth necessary for the construction of an extension. The bottom of the trench must be covered with a layer of rubble. Each of the layers must be carefully compacted.
From wooden planks formwork is being prepared for pouring concrete. Its height should be equal to the height of the future base. An important point is that it is necessary to carry out waterproofing work around the entire perimeter of the future foundation, as well as to lay metal reinforcement to give strength.
A third of the installed formwork is poured with prepared concrete mortar until completely solidified. Subsequently, the remaining part of the cement is poured with the removal of air bubbles using a special vibrator or tapping the formwork walls with a hammer.

On a note

The upper part of the fill should not only be leveled at a single level, but also covered with a film for more thorough drying. Light wetting of the surface is recommended to prevent cracks.

Floor covering installation

We found out how to attach a frame extension to the house with a high-quality foundation, now we'll figure out how to install the floor. There are two ways to install the floor:

Wooden floor installation.

Concrete, most suitable for an extension with strip foundation- which will provide the greatest stability of the structure. The soil inside the already installed foundation is dug to a depth of about 350 mm. The bottom of the resulting niche, as well as the foundation trench, is covered with sand and gravel, or a 20-centimeter layer of expanded clay is covered, for better insulation.

If the extension to the house is frame, then with the help of the level, beacons are installed for further pouring the cement floor screed, on which tiles are already being laid, wood flooring, or flooring appropriate for the purpose of the room. IN cement screed it is easier to lay a floor heating system, if one is planned.

It will be more economical and environmentally friendly to install a wooden floor. According to him, a bookmark occurs beam floors installed above the waterproofing membrane. Fastening wooden beams to the foundation occurs with the help of special anchor bolts.

Corner joints of floor beams installed along the perimeter of the foundation of a frame extension to a wooden house are made according to the type of lock joints. Next, the transverse beams of the floors are mounted, layers of insulation are laid and top coat extension floor.

Extension installation

They will tell you more precisely how the frame extension to the house is mounted video and photo reports from real objects.

In short, the do-it-yourself frame extension to a wooden house and the most important part, its base, are mounted as follows:

With the help of dowels and a perforator to the floor and the first wooden crowns wooden bars are mounted;
The vertical beams of the frame are installed around the perimeter of the foundation of the extension and the places where future doors will be installed, in increments of no more than 70-100 cm;
To give strength to the frame extension, transverse floor beams are mounted;
If installation of the second floor of the extension is necessary, it is necessary to carry out additional strengthening of the ceilings of the first floor.

Fastening to a wooden building

One of important points construction of a frame extension to a wooden house - carrying out its docking with an already built structure.

If the selected materials do not match, the depth of the foundation or other specifications, then it is necessary to perform an expansion joint at the junction of the foundations of the old house and the extension.

Annex by frame technology.

Work can be done in two ways:

Laying roofing material between parts of the foundation, if their parts are even and vertical.
Laying foamed polyethylene and expanded polystyrene at the joints with filling the upper part with sealant and a special closing pad.

Roof

If the simplest type of roof is chosen - single-pitched, then the installation of floors occurs quickly enough:

The beams are mounted at an angle - from the slope to the vertical beams of the extension with a protrusion of at least 300 mm;
OSB sheets, plywood or frequent rows of battens are laid for final assembly roofing;
Actually, finishing touch there will be installation of the selected roof - slate, iron sheets, tiles or other options;
sheets mineral wool laid between the rafters;
The insulation is masked by the lining OSB sheets and decorative elements.

Warming

One of the final stages of construction - the process of insulating an extension to the house - also depends on the intended purpose of the future building. If the building is not intended for year-round living, then the most economical type of insulation is selected, or work to preserve heat indoors is not carried out at all - when choosing a summer type of construction.

Do-it-yourself warming.

In other cases, insulation layers are laid not only during the installation of the floor and roof, but also at the stage of sheathing the frame racks with sheets of OSB boards. consists of:

Internal lining.
vapor barrier membrane.
layer of insulation.
windproof material.
External cladding.

Insulation of the frame extension to the house can be carried out using mineral wool from the middle price category, or more expensive eco-wool, but environmentally friendly and treated against fire and.

Finishing

The final stage of construction is Finishing work inside the frame extension. They depend not only on the purpose of the premises, but also on the costs that the owner of the house is willing to bear. However, when choosing an installation, one should also take into account the type of foundation laid and the reliability bearing beams– heavy coatings will significantly reduce them.

The construction is made on a frame basis, which consists of bars or planks made of metal. After the installation of the frame structure, the walls are clad on both sides. In this case, OSB or chipboard plates are used. Heat-insulating material is laid between the plates. It can be polystyrene foam or mineral wool.

By thermal insulation properties frame structures are not inferior to more solid stone or brick buildings.

The extension must be connected to an existing building. Usually, the same foundation is made for the structure as for the main building.

For residential premises, create separate foundation and a custom wall. The void and the gaps between two walls are blown out mounting foam. This will prevent damage to the wall of the building when the new extension shrinks.

A more economical option for the foundation is pile. The walls are built from profiled timber. After installing the first row, the surface of the tree is treated with antiseptic compounds. Then lags are mounted on it. Voids and cracks are filled with special heat-insulating material.

Each row is fastened with wooden dowels. special attention requires installation of corner zones. For this, logs with a ledge and a groove are used for a stronger grip.

For your information! Reinforcement is used to unite the two foundations.

Before proceeding with the construction, one should take into account some of the nuances of installing an additional structure to the main structure. The length of the new structure should be in harmony with the length of the main building wall. The width of the additional structure can be any.
