How to properly attach an extension to a house from a bar. Flooring and interior work
Extensions are built for 2-3 years after the end of the main construction. There are two reasons for such an addition to the main house: either there was not enough money during the main construction for larger area, or the main structure does not provide for a veranda or terrace.
Among construction companies, this is a popular service, but in order to save money, most often the work is done by hand. Especially ready-made options You can see a lot on the video and photo on the Internet. About how to mount an extension to a house from a bar, what it should be will be described below.
What you need to start building
Project outline for an extension to wooden house
Any extension to a wooden house is independent construction houses from a bar, requiring its own project and calculations. Moreover, docking with a bar must be done so that subsequently no cracks appear. At the same time, one should not forget about architectural solutions. The extension must harmoniously fit into the entire structure.
For the construction of an extension in a residential building, the permission of the architectural committee of the city and the support of all documentation are required. You can properly plan the extension yourself, but this requires skills.
House planning companies offer a service for drafting an extension to a wooden house from 25,000 rubles, depending on the region. Such a solution is convenient in that the finished version can be viewed on the proposed photos from the company manager. Moreover, it is difficult to use a typical one in such a situation, since the annex is located individually in each individual case.
What are the extensions
The construction of the adjoining wooden structure can be framed and frameless. You need to choose a design based on: the number of storeys, the area of \u200b\u200bthe annex, the availability of free land, the types and features of the house. by the most in a simple way the construction of an extension of the same material as the main house is considered. So the construction of a house from glued laminated timber involves the same extension .
So if the main structure is made of glued laminated timber, then it is better to make an extension from it. Otherwise, shrinkage occurs in different ways, and gaps appear in the joint. At the same time, technical performance characteristics material.
The annex is mainly mounted to the wall of the facade, there are many similar photos on the network on construction sites. According to the number of floors, it can be one and two-story building. According to the roof structure: pitched one-sided, under a common roof.
Attachment from a bar at proper planning suitable for houses made of brick, wood, blocks, etc. Structures not related to the main structure common foundation and bearing parts can be assembled by hand. But if a timber extension to a brick or cinder block house, then construction can cause a number of difficulties. It is better to entrust such work to professionals.
Features of the installation of a timber extension
Installation features largely depend on whether the structure will be residential or not. During the construction of a residential wooden extension it is necessary to mount a separate foundation, a connecting wall, provide a communications system.
With this installation, the main house and the extension are not connected by fasteners, and are separated by an expansion joint. This seam is needed to shrink the extension. It is movable and breathable, which makes it possible not to damage the extension walls.
To a wooden house, a frame-beam extension is most often made. The extension is being insulated, and I am doing the finishing for the main house. Also used internally finishing material. So, additional walls are attached to the main structure using metal brackets, plates, brackets, etc.
Main stages of construction
The main parts of the extension installation:
- Calculation and purchase of material
- Foundation installation
- Roof
- Finishing
We will talk about each of the stages in more detail below and look at the proposed video:
Calculation and purchase of materials
Before construction, they think over the location of the extension from the timber and its number of storeys. The amount of purchased material will depend on this.
For calculations, you need a project for the future extension. It is budgeted for. You can calculate the amount of material using the same calculator that is found on many construction sites.
You need to decide what shape the roof will be. The easiest way is to perform a one-sided pitched. The roof is the same as on the main house.
Foundation installation
The foundation is selected depending on what the building will be. A separate foundation is made for a residential wooden annex. Its depth should be the same as that of the main structure. The connections of the main foundation with the extension are carried out using reinforcement. If this part is missed, then over the years the two foundations may diverge.
The main stages of foundation installation include:
- Markup is being done.
- A ditch is dug to the depth of the main foundation.
- Mounted formwork from wide boards.
- A reinforced bond is made, including with the main foundation.
- Filled with concrete.
At the stage of installation of the foundation, it is important to perform waterproofing. To do this, use roofing material, which is placed on top of the foundation. For a more hermetic design, you can coat the foundation with a bitumen solution.
For a veranda or a track, a lightweight type of foundation on piles is suitable. Do-it-yourself installation is easier and more economical.
The walls are erected in the same way as under conventional construction houses made of profiled timber or other lumber. But, don't forget about expansion joint. It is subsequently filled with mounting foam.
If the main house and the annex are of the same material, then the walls can be connected using fasteners. So dowels are made in a beam of 5 cm. Using screws and plates, they connect the main wall and the extension. For the same purpose, metal staples are used. They are fixed every 2-3 links.
If the building is lower than the main wooden house, then the roof must be made with a large slope so that water and snow do not accumulate at the junction. Additionally, it is not necessary to connect it to the main structure. For greater strength, it is possible to drive an additional beam in increments of 15 cm.
If the annex is two-story warm, then the roof can be connected to the main one. To do this, part of the main roof is dismantled, the ceilings are connected using iron corners. Then waterproofing and roofing is done.
When installing the roof of a two-story outbuilding, do not forget about the drainage system. It is necessary that the design of the drainage system was integral.
The price of an addition to the house
The main price of an extension from a bar consists of several factors:
- Method of construction and type of construction.
- One or two floors has an annex.
- The complexity of the foundation design.
- Beam type.
- The complexity of the architectural solution.
Average price for an outbuilding:
To these works you need to add delivery, finishing, insulation, drawing up a plan, estimates, windows and doors, grinding and coating, etc.
In addition, do not forget that the annex must be warm. It needs to be insulated both inside and out. What materials are suitable for insulation wooden walls, we have already discussed in
You can calculate on your own how much an extension to the house will cost on your own. On average, the construction of a turnkey extension from profiled timber comes out from 15,000 m 2, from ordinary from 7,000 m 2, from glued from 25,000 m 2.
How to cut costs
- You can save money by purchasing winter time. bar natural humidity will correspond to chamber drying, and the price will be lower.
- You can pour the foundation yourself, this will reduce costs by 20%.
- Hire a construction team in the winter, when the construction season is off and the price is lower.
- Purchase used material or leftovers from ads.
- Make the extension frame and finish with an imitation of timber.
How to mount the extension, with your own hands, or invite specialists, the owner decides. But by doing the work yourself, you can make mistakes that are difficult to fix after construction.
In most cases, every owner of a wooden house sooner or later decides to make an extension from a beam with his own hands to the main building. Typically, building additional premises carried out 2-3 years after the completion of the construction of the main building. This can be explained by two factors: lack of funds during the construction of the house or the absence of this element in the original project.

Such work can be done quickly and efficiently construction companies who have a large staff and years of experience. But in this case, it is necessary to prepare for considerable material costs. In this case, it is more profitable to do all the work yourself. On the this moment there are a lot of ready-made options and projects that can be quite simply translated into reality on your own.

Like any building, an extension must begin with a choice optimal design and making calculations. At the same time, special attention is paid to joining the timber with the main building in order to avoid the occurrence of cracks. Also, do not forget about obtaining the necessary permits from the architectural committee and collecting all the necessary documentation.
As for creating a project, you can do it yourself if you have the appropriate skills. Otherwise, you will need to seek help from professional architects who will be able to realize your ideas on paper.
Creating a plan for a future extension
If you are the proud owner of a plot with large area, then there will be no special problems with the construction. To do everything right and not make mistakes regarding the size of the rooms, you need to draw up detailed plan. In doing so, the following recommendations should be taken into account:
- The first step is to decide on the main purpose of the annex, since it is not always used as a living space. Such extensions can be used as a garage, workshop or veranda. The size of the object, the quantity and quality of building materials, the type of window structures and much more will depend on this.
- Also, in the process of creating a project, it is worth considering the need to supply communication systems, such as sewerage or water supply.
- Do not forget about the choice of the main material. Logs have significant differences in their quality, characteristics and price.
- All this will allow you to get a relatively accurate estimate for everything. construction works.
An extension from a bar is most relevant to build for wooden houses. In this case, it is necessary to equip a separate foundation for the extension, which will be connected to the monolith of the main building.
Varieties of outbuildings from a bar. A photo
Initially, it is necessary to understand that wooden outbuildings can be of two types, namely frame and frameless. When choosing optimal design it is necessary to build on such indicators: the number of storeys, the area of \u200b\u200bthe future structure, the type of house, the availability of free space on the site. The most simple and optimal solution is erected from the same material as the house itself. If you built housing from glued laminated timber, then the extension must be made from it.
If you choose a different type of wood, then shrinkage will take place in different ways. This can lead to the formation of gaps at the joints. Such technical and operational characteristics must be taken into account at the design stage.
The annex must be mounted to the facade of the building, on the network you can find a huge number of photos and videos that demonstrate best options. If you have enough money and time, you can even build a two-story extension.
Thoughtful design allows you to equip a wooden extension even for brick or block house. It should be noted that structures that do not have general connection from load-bearing structures and the foundation, you can quite simply build it yourself, of course, when it comes to wooden structures. If you need a wooden extension to brick house, you need to conclude with the help of professionals, since many difficulties will arise.Frameless outbuilding. A photo
This category of buildings includes structures made of logs, timber and cylindering. This is a great option since the base material has the same characteristics as the main building. Accordingly, shrinkage will take place evenly and without distortions.
The advantages of these designs:
- If you are purchasing material ready-made kits from required dimensions, then the construction will not be a problem.
- Such designs will correspond to the environmental friendliness of the house.
- This type of extension does not require additional finishing work.
- The connection to the house is made by plates with screws or brackets.
Design flaws:
- If moisture is used, it will shrink significantly, which will lead to skew.
- Sometimes, when drying, longitudinal cracks may appear on the logs.
- For insulation, additional caulk is needed.

Initially, it is necessary to understand how the building will be used. If this is a dwelling, then it is necessary to mount a foundation separate from the house. In addition, it is necessary to equip a quality connecting system. Before starting construction, it is necessary to think over and lay all communication systems.
In this case, there is no need to use brackets or plates for docking with the house. At the same time, a minimum expansion joint remains, which will avoid trouble during shrinkage. It will allow the extension to move quietly when the material dries, without any damage.
In most cases, the best option is a frame-timber extension. At the same time, they carry out additional insulation and an external department, the same as that of the main house.
The main stages of building an extension from a bar with your own hands
- Project selection and materials calculation.
As in any construction, initially there is a thorough study of the location of the extension and what configuration it will have. The quantity directly depends on the size and number of storeys necessary materials and material costs.
You can create an extension project yourself or seek help from architects. Based on it, you can calculate a fairly accurate estimate. To do this, it is enough to arm yourself with a calculator and find out, at least approximate, the cost of the necessary materials. Prices can be obtained by monitoring construction sites.
At this stage, it is worth deciding on the type of roof. The easiest to build and financially advantageous is pitched roof. For a harmonious appearance, it is worth using the same roofing material as on the main house.
- Installation of the foundation for the outbuilding.
The type of foundation is selected depending on the design of the future structure. For a residential extension, it is necessary to build a separate foundation. Its depth should be the same as in the main building. Nevertheless, it is necessary to carry out reinforcement between the foundations. If you do not do this manipulation, then over the years they may disperse.
The construction of the foundation consists of the following stages:
- The first step is the marking along which the moat will break out.
- The depth should correspond to the depth of the main foundation under the house.
- Further, a reliable formwork from wide boards is installed on the ground.
- For strengthening, reinforcement of the structure is carried out.
- The last step is pouring concrete.
At this stage of construction, special attention must be paid to the waterproofing system. It can be created using roofing material, which is laid in several layers with a coating of bitumen solution.
- Installation of extension walls. Photo, video.
The construction of the walls of the extension from the beam is carried out using the same technology as conventional construction. This can be seen in the photos and videos pointed in this article. When laying the timber, it is necessary to remember about the deformation of the seams.
A feature of the annex is that one of the walls is common with the main house. Because of this, only three walls need to be erected. Depending on the configuration of the house, it is enough to equip two walls for an extension. As for the connection of two wooden structures, it is carried out using metal plates with bolts or brackets.
During construction, the following recommendations should be considered. If you plan to use the extension as a living space, then you must use a beam of at least 200x200 mm. At the same time, it must be remembered that wooden structures require shrinkage, which takes about one year. The exact time depends on the massiveness of the extension and the quality of the wood used. Because of this, the connection of the new building with the house should be as strong as possible.
After the final shrinkage of the extension, it is necessary to remove the old brackets or plates and install them in new positions. It should be noted that in the process of shrinkage, it is necessary to carry out measures for warming. In most cases, felt or mineral wool is used for this.
To give the extension more attractive appearance and protect against heat loss, use special flashings. In the process of shrinkage, their deformation may occur, so they need to be dismantled and fixed again. After the construction of all the walls on the last crown, a beam with a smaller size is laid, which will act as a roof trim.

If the new building is lower than the main house, then you need to think about the choice the best option roofs. In this case, there should be a large slope angle, which will ensure effective removal of snow and water. The main thing is to ensure the tight connection of the roof of the annex to the house. To increase the strength, it is necessary to use an additional beam.
In the case when you have built a two-story warm extension, it is better to connect the roof to the main one. To make a reliable connection, it is necessary to disassemble part of the main roof for the highest quality connection of the floor. At the same time, do not forget about the waterproofing and insulation system. The last step in the arrangement is the arrangement of the drainage system. For this, one-piece structures are used.
- After that, the flooring is laid or the crate is arranged.
- The next step is facing the gables new roof and hemming of all cornices.
- Installation of wind elements.
- Laying the finish roofing material taking into account technological features.
As for the material for the roof of the extension, the best solution would be to use the same as on the house. Of course, you have the right to decide for yourself, there are no special restrictions.
Recommendations for the construction of an extension from a bar with your own hands
Professionals say that construction wooden structures better in winter period. This is explained by material will pass climatic tests and temperature changes, respectively, shrinkage will be faster.
To preserve the unique and natural appearance bursa, insulation must be installed from the middle of the room. If you have carried out a competent installation of the sealant between the logs, then the need for a heat insulator may disappear. In most cases, 50 mm foam padded with inside walls for excellent heat retention in the annex.
To increase the service life of the erected extension, it is necessary to carry out additional protection timber. This is done with a special antiseptic treatment. Do not neglect the fire-fighting equipment, which will significantly reduce the ignition factor.
When erecting an outbuilding from a bar, it is necessary to use a minimum number of metal fasteners. This material is susceptible to corrosion, which will lead to a violation of the overall integrity of the structure.
Do-it-yourself extension price from a beam
The cost of building a wooden outbuilding depends on the following factors:
- Construction type and construction technology.
- Floors of the extension.
- The type of foundation and the amount of materials needed.
- The choice of building material for the walls. Beam type.
- The complexity of the architectural project.
You can do the following to cut costs. Make purchases of materials in the winter, when they fall most in price. At self potting foundation can save all costs by 20%.
Of course, you have the right to choose the most optimal building materials that can fit your budget. All of the above recommendations, photos and videos will help you build an extension from a bar with your own hands.
Life can turn out in such a way that your large family will begin to live closely in a house made of timber. Adult children will get families and want to stay with their parents, and there it’s not far from grandchildren. So that the housing issue does not spoil the relationship between loving and dear people, there are perfect solution- expand existing living space by making an addition to the house. In this article, we will look at how to do it correctly and profitably.
Fig1. Even the extension of an ordinary veranda will take time and effort, since it is being built for many years.
The project is the first stage of construction
If you already have your own plot on which the house is built, and there is enough space for other buildings, it will not be difficult to expand the living space with a new extension. And numerous assistants - your relatives - will help you do all the work with your own hands.
The first stage of construction is, of course, the creation of a project.
When starting to design future extension premises, pay attention to such important points:
- Determine the purpose of the space: how will your extension be used? For example, it can be living rooms or a warm garage, workshop or bathroom. The choice of material, the number of windows and much more directly depends on the operating conditions of the extension.
Fig2. As a rule, the extension is built as part of the house: it is cozy and in rainy summer days, and in winter, over a cup of tea
- Find out how it goes network engineering on the site on which you plan to build an extension. It is necessary that sewerage, water supply, gas pipelines and other communications are not damaged and can subsequently be freely serviced, repaired, etc.
- Decide on building material. It must be clearly understood that the selected material will affect not only the construction technology, but also the cost and service life of the structure.
- Decide what type of structure - frame or solid (stone, wood) you will build.
An extension from a bar: proceed to the construction
Regardless of whether you live in a wooden or stone house, if you decide to make an extension to it, then you need to start with the foundation.
Foundation device
The foundation for an extension from a bar must be carried out according to the same technology as the foundation for the main building (actually, a house from a bar). If you built a house with your own hands, then you know absolutely everything about the construction of its foundation, which means that it will be much easier for you to repeat this experience for an extension.
You need to take into account:
- foundation dimensions;
- foundation depth;
- foundation material and method of its construction (i.e. whether it is monolithic or prefabricated, concrete, reinforced concrete, stone, cinder block, foam block, etc.)
Fig 3. Foundation construction can be done at any temperature and at any time of the year
Make the foundation for the extension using the same technology as for the house - and you can start building walls.
But it may happen that you do not know anything about the foundation of the main house. What to do in this case? You need to find out the information you need. First, you will have to dig the ground near the house in the place where the extension will be, to the very foundation. Then examine the piece of foundation that has appeared for all the characteristics that were described above. After that, you can start laying the foundation for the extension.
After the new foundation is completed, it needs to stand without load for about a month or even more: during this time it will become strong. Careful attention is required at the junction of the new and old foundations.
Fig4. This is how an extension is erected on a columnar and monolithic-tape base
Walling
The next stage of construction is the construction of the extension walls on a new solid foundation. Usually it is not necessary to build all 4 walls, but only two or three are enough - depending on the configuration of the house, to the walls of which the new room will be completed. As a rule, the connection of the walls of the old and new buildings is carried out without much difficulty, since the same building material (wood) is used.
Fig 5. In this way, using cemented reinforcement, the base of the timber is installed and attached to the foundation
As fasteners you can use:
- metal staples;
- metal plates;
- nails;
- self-tapping screws;
- brackets, etc.
In order for the shrinkage process to be completed completely, it takes about a year, but sometimes more. The timing depends on several factors:
- extension dimensions;
- percentage of wood moisture;
- the period for which the shrinkage of the old house occurred.
Do not rush to operate the new extension, wait until the shrinkage process is over, as there may be a vertical shift between the house and the new building. How to fix the situation: pull out the staples that are warped, install them again, already straight. Typically, this will only need to be done once.
It is highly desirable to insulate the extension for the time that shrinkage will take place. Suitable for this mineral wool, tow, felt, isover.
To complete the installation of the roof and attic, you need to tie new and old walls around the entire perimeter with a beam, the cross section of which is smaller than that of bearing walls(suitable size 150 x 150 mm). The crown is best done with bars without joints. Whether this is possible depends on the size of your building, but even for large structures, you can order a beam up to 12 m long. However, this option is very expensive compared to traditional sizes, the most common of which are 2 m, 3 m, 6 m.
Roof device
The roof common to the entire resulting building is erected along traditional technology for a wooden house. The roofing device is the next stage, which can be divided into the following processes:
- installation of the truss system (installation of racks, slopes, crossbars), taking into account not to exceed the maximum load parameters of the structure;
- lathing from a bar (another option is a solid flooring from boards), is carried out along the rafters;
- facing of gables;
- arrangement of cornices;
- installation of wind elements;
- laying roofing (material - optional).
Fig 6. It is important that the roof is installed at such an angle that the snow can easily slide off it, otherwise additional snow load can lead to destruction
The final stage is the installation of the floor, the installation of ceilings and the decoration of the premises. Installation of windows and doors is carried out in the annex in the same way as in the house. It is better to use wooden window structures and doors. Now the work on the construction of an extension from a bar to a wooden house is completed!
Sometimes it may be necessary to build an extension from a bar to a brick house. What will be the difficulties? First of all, in how buildings from different materials at the junction.
Fig7. Extension to a brick house: wooden supports and glass are originally combined
- A wooden extension cannot be securely and firmly held near brick house. The hitch (fastener) should be thought out very carefully.
- Wood is much more hygroscopic than brick. In problem areas, the timber must be carefully treated with impregnations.
- Waterproofing between brick and timber should be of the highest quality and reliable.
- To prevent drafts and freezing at the junction of walls made of timber and brick, install a good and movable seal.
Fig8. Jute felt or tow is an excellent sealant
In all other respects, the technology for building an extension to a brick house resembles the previous version (with a wooden house). They choose an extension from a bar precisely because it is cheaper than a brick one. Although, in fairness, it should be noted that in a brick house it is better to build an extension also made of bricks.
Lumber preparation
Finally, it is impossible not to touch on the issue of purchasing timber for construction. Before purchasing lumber, you need to make sure that its parameters meet the requirements of the project, that is, we are talking about the following characteristics:
- the length of the beam and the cross-sectional area;
- timber moisture level;
- observance of geometric parameters along the entire length of the timber;
- the type of wood from which the beam is made.
Do not forget that these are the main characteristics of the timber, on which its price and performance. Please check all items carefully before purchasing.
Conclusion
As you can see, building an extension from a bar is very simple, no matter what material was used to build a residential building. It is only necessary to take into account the basic rules for working with wood: during construction, strictly observe fire safety requirements and give the new building time to shrink. We wish you successful construction of an extension with your own hands. And the video clip posted to this article will help you in such an interesting business and tell you a lot of useful tips.
It is not uncommon for a family to grow quite actively, especially when children grow up, start families of their own, and grandchildren are already running around your house. The housing issue is acute. And since not everyone today can afford to resettle children in their own home or the family prefers to live inseparably in several generations, it remains the only way out- expand existing housing.
The project is the basis of any construction
Owners of private housing construction, if, of course, there is sufficient space for personal plot, this is easy to do. Even if you decide to do everything with your own hands, we do not see any obstacles, especially since the house is full of assistants.
Let's start with the layout of future premises in order to understand what size our extension to the main house will be.
What is important to consider when designing additional space:
- The purpose of the attached premises (sometimes an extension is conceived for the purpose of arranging a workshop, a bathroom, a warm garage with access directly from the house). Everything depends on this, from building materials to the number of window openings.
- Presence on the site allocated for construction, engineering communications(water supply, sewerage and much more). These facilities must be easily accessible for maintenance and possible repairs.
- What materials will we build from? This question should be asked to yourself long before you start learning the basics of design, construction material affects not only the price of the entire project, but also the durability of the structure.
- Consider the format of completed structures.
- Frame walls.
- Solid stone or wood.
Wooden extensions to a wooden house
In this section, we will touch on the option of an extension from a bar to a wooden or stone house. Whatever building we are attached to, we should start with the foundation.
Foundation
When an extension is erected from a bar to a wooden house, the foundation should be laid under it the same as under the main structure.
The easiest way in this regard is for those who built the house on their own and know everything about its foundation:
- Dimensions.
- Depth of laying.
- The design and material of the base.
- Monolithic.
- Concrete.
- Reinforced concrete.
- Made.
- Reinforced concrete.
- Stone (cinder blocks, foam blocks, etc.).
It remains only to repeat such a foundation for an extension, tying it to the existing one and ready, you can build walls.
In the case when an extension to a wooden house made of timber is carried out without information about the existing foundation, research work will have to be carried out:
- "Dig out" old foundation from future construction.
- Examine it according to the above parameters.
After the device of a new base, let it settle, gain strength for at least a month. Special attention when constructing a new foundation, allocate places for its docking with the old one.
Note! The easiest way is to use the installation of a pile foundation, since it does not depend on an existing foundation. It is enough to drill several recesses and drive (screw) supports into them.
Walls
Now the instructions for the further process - on the finished foundation, we begin the construction of walls.
You must have planned the device:
- Three additional walls, and the fourth will serve as the wall of the existing house.
- Two with a suitable configuration of the old dwelling.
Since this is an extension from a bar to log house or from similar lumber, joining new walls with old ones will not be particularly difficult.
How fixing material will fit:
- Staples are metal.
- Metal plates.
- Brackets.
- Self-tapping screws.
- Nails, etc.
Important! Attachments from a bar for permanent residence people are usually arranged in it from lumber with a cross section of at least 200x200 mm. It should be remembered that this is a rather heavy building material, which will definitely shrink.
Therefore, fastening at the junction of old and new walls (where an extension to the house from a bar is located) is carried out with a bracket and left alone until the final shrinkage.
The shrinkage period according to specialized sources can last about one year. But it may take longer.
Everything here is not clear and depends on several conditions:
- Outbuilding dimensions.
- Degrees of humidity of initial raw materials.
- Terms of shrinkage of the old house.
In any case, you should be patient and not rush. After the expiration of the shrinkage period between existing building and a new extension, an offset is possible, as a rule, vertically.
It is necessary to pull out the skewed staples and nail them again without displacement. Usually one such procedure is sufficient.
To prevent the wind from walking in your extension during the shrinkage period, fill the vertical slots with any insulation available to you:
- Mineral wool.
- Isover.
- Tow or felt.
For your information! For an aesthetic look and to enhance the effect of the seal, close the joint with a wooden flashing. If it "pulls", dismantle and nail it again.
On top of finished new and old ones with a smaller section (for example, 150x150 mm). Belt - the crown is laid around the entire perimeter.
Ideally, if the strapping beam is without joints, but it all depends on the size of the resulting structure. Although according to custom order you can make a beam up to 12 m long, only it will cost several times more.
On the construction market more practical sizes of 2.3 and 6 meters are more common.
Roof
Now we arrange the roof of our expanded house. This work is being done in the usual way according to the well-known technology in the construction of roofs from wooden structures.
Schematically, the process looks like this:
- We install the truss system (racks, slopes, crossbars), observing maximum load to the design.
- On the rafters we make a crate from.
- We cover the pediments.
- We hem the cornices.
- We install wind elements.
- We mount roofing from materials of your choice.
It remains to install the floor, filing ceilings and Finishing work. We install windows and doors in the extension in the usual way.
If you want to install an extension to a brick house made of timber, you should take into account some features of the behavior of joints from such different materials:
- A wooden extension made of timber to a brick house will be non-static in relation to the brick neighbor. Connection devices need to be carefully considered.
- Wood is highly hygroscopic. Reduce this property at the ends and other problem areas timber can be treated with special impregnations.
- Be sure to arrange high-quality waterproofing at the junction of wood to brick.
- Also at the junction of wooden and brick walls it is necessary to arrange a movable seal to avoid drafts.
Otherwise, an extension from a bar to a brick house is being built according to the above technology. Of course, brick outbuilding to a brick house would be more harmonious, but the price of a wooden one is much less. Therefore, many are leaning towards this option.
For your information! You can easily finish the facade of a cheap bar facing brick or decorative stone imitating a brick. Such a process will not take much time and effort, you can do all the work with a screwdriver and without assistants.
Lumber harvesting
In conclusion, I would like to say a few words about the purchase of timber for construction.
In the process of purchasing lumber, you should pay attention to the compliance of the latter with the stated requirements:
- Section and length parameters.
- Wood moisture levels.
- The correctness of the geometry of the beam along the entire length.
- Species of wood from which the beam is made.
All this directly affects the cost of lumber and therefore deserves close attention.
Life goes on as usual, from time to time throwing up new tasks, one of which is the need to expand the living space. An extension to a house of a capital or non-capital nature will help with great comfort solve economic issues, will add square meters a useful area where you can organize a cozy tea party or install cabinets for storing things. The goals are different - the solution is one. Timber extension. The option is good affordability and the ability to do it yourself.
Draw - let's live
Everything needs to start with a project. The drawing will help to provide for all factors, design features, stages of work, right choice materials will lead to cost optimization.
To begin with, you should evaluate the possibilities of the site for an extension, plan the size of the room, but the main thing is to determine the purpose. What will it be, living room, veranda, workshop, and maybe a garage. It will be a heated or cold room. What will be the use of the premises, seasonal or year-round, whether communications are needed, heating, plumbing, how to glaze, which doors to install, and what thermal insulation to use. All questions will be answered by the project.
What material to choose for the walls. The most rational would be the use of timber. Glued, rounded or planed timber has undoubted advantages, including:
- affordability;
- excellent performance characteristics;
- external attractiveness;
- environmental Safety;
- the speed of building walls;
- the possibility of building with your own hands;
- use of a light foundation,
an extension from a bar can be done in winter, freeing up summer time for labor-intensive seasonal work.
Important! Drawing up a project will determine required amount timber, insulation, fasteners, roofing materials and other things. Having prepared everything you need, you can get down to business.
Foundation for an extension
The foundation of the extension should correspond to the foundation of the house, but it is not at all necessary to equip a powerful monolithic base for an extension made of timber. Enough tape or pile foundation. It is important to pay attention to the junction of the foundation of the extension to the main one.
For the installation of a strip foundation, the following measures will be required:
- dig a trench to a depth corresponding to the level of soil freezing in the region (for middle lane Russia 1100 cm), a width greater than the width of the beam by 4-5 mm (if a beam of 200x200 is planned, the width is 205 mm, respectively);
- make a pillow of sand and gravel;
- install reinforcing cage;
- pour concrete.
Bring the foundation as close as possible to the base of the house, fill the gaps with concrete mix.
For a snug fit to the house on the beam, equip special fasteners, dowels, which are connected with screws to the plates attached to the house, but this is later, and at this stage waterproofing should be done, for which cover the top of the foundation with bitumen and fix the roofing material on top. And after the foundation is settled, in a couple of months you can start building walls from a bar.
Important! Strip foundation reliable, but its construction is laborious, dependent on weather conditions. No worse than the pile-screw type of foundation, the technical and operational characteristics are the same. Its arrangement is much easier, faster and cleaner. Not construction debris, the terrain remains clean intact.
After arranging the foundation, communications, plumbing and drainage, if required, should be laid. And don't forget the ventilation windows.
Walling
The peculiarity of the construction technology of the extension is that only three walls are installed, the fourth - common wall with the house. Connecting material for timber, nails, staples, self-tapping screws, mounting plates are used for better fastening, strength.
Profiled timber does not require insulation, other types require laying jute fabric. A warm extension, intended for all-weather use, is erected from a 200x200mm timber, it is less prone to shrinkage.
Advice! Purchase a profiled timber with a residual moisture content of not more than 12%, treated with flame retardants and antiseptic compounds. Well-dried timber gives little shrinkage.
However, shrinkage cannot be avoided, so experts advise using flashings. These are fasteners that fix the laying of the beam until it dries completely, then they are replaced with new ones for the final fixation of the walls.
The upper beam of the walls of the extension or the strapping is laid around the perimeter like all beams. For strapping, a beam of a smaller section 150x150 is used; this link serves to connect to the roof.
In the process of building walls, you need to monitor the tightness of the joints, in the end, you can outer side cover the timber with a composition that increases its hygroscopicity.
Advice! Pay attention to the primers that enhance the hygroscopicity of Monolit-Hydro, the German agent Biofa, Senezh and other compounds with a waterproofing effect.
The walls are ready, it's time to start arranging the roof.
Installation of the extension roof
The roof of the extension, as a rule, has a shed shape, the roof material is identical to the material of the main roof. truss system shed roof easy to manufacture. For rafters, a beam of 150x150 is used if the span is more than 4.5 m in length and 100x150 if the span is less than 4.5 meters.
The strapping can serve as a power plate, the rafter pitch is 60 - 140 cm, if the angle of inclination is from 5 ° to 20 °. The value of the angle is directly related to the arrangement of the junction with the main roof. A higher slope contributes to better snow removal.
Depending on the material of the roof, they make a crate, use a tes, a slab to reduce the cost of construction. It is more pleasing to the eye when the roof of the extension and the house represents single structure, however, you can not combine them.
Important! If the roof of the extension is lower than the main one and exists as a separate structure, care should be taken to seal and thermally insulate the junction.
The arrangement of the roof ends with the sewing of gables, cornices, installation of wind elements and roofing.
Important points to consider when building an extension from a bar
Particular attention is the docking of the extension with the house. Each crown is attached to the main wall with mounting elements. The joints should be impregnated especially carefully. special formulations, seal the junction with high-quality waterproofing materials.
It is better to place heat-insulating materials on the inside, so the operating time will last, and the appearance of the wooden extension will be preserved in all its glory of the natural pattern.
The use of metal fasteners should be kept to a minimum, or galvanized fasteners should be used to avoid corrosion.
Doors and windows should not be installed immediately, it is advisable to install them after the final shrinkage of the tree.
If the extension is made as a continuation of the house, looks like a single continuation of it, then it is done correctly, its operation will be long and prosperous.
