Do-it-yourself brick extension to a country house. How to make an extension to a wooden house with your own hands. Simple extension to a wooden house

Modern construction experiencing a rebirth frame technologies. From a wooden beam, edged boards and panel panels, houses and cottages are built that are not inferior in comfort and durability to buildings made of classic materials. The idea of adding an extension to a house from a frame is attractive because to build a room attached to the house, you don’t need to bother with concrete and masonry blocks, you don’t need modern construction equipment, and most importantly, you can do most of the work frame extension To wooden house with your own hands, sometimes without even resorting to the services of assistants.

How to build a frame extension

Technology frame construction assumes for the manufacture of a load-bearing frame of an extension edged timber and boards. The methods for constructing individual parts, walls and roofs of a frame extension to a house are practically no different from the construction of conventional wooden frames for a barn gazebo or even a wooden house.

A frame extension to the house can be built in several options:

A classic frame made of boards, slats and timber, reinforced with spacers and struts made of boards with insulation based on mineral wool or expanded polystyrene;
A combined version of a power frame made of timber and SIP panels. The vast majority of construction companies build extensions from a frame using only panels and timber;
Frame base made of timber, insulated basalt wool and lined with siding. In this case, the skeleton of the walls and roof is made according to a reinforced design, and the finishing of the facade is selected to match the color and texture of the walls of the main building.

For your information! Usage wooden frame and siding allows you to design the extension and the house into one whole. It is quite difficult to visually distinguish which part of the building is permanent and which is made in the form of an extension from a frame.

On the other hand, the use of siding sharply increases the load on the extension frame; you have to use more expensive lumber, buy loops or lining for interior decoration walls, pour a more massive foundation.

Construction based on a frame and siding is justified for rooms measuring no more than 3x5 m. It is more economical to build larger boxes from foam blocks, and a frame for small outbuildings, as a rule, are assembled from 70x90 mm timber and edged boards.

The main question of building an extension

The construction of any extension based on a wooden frame begins with the selection of a place for installing the attached premises and a rough marking of the future foundation is carried out. Correct selection The foundation design guarantees the durability of the structure; simply copying the foundation structure, like the frame of a barn or a wooden gazebo, most often ends in the breaking of the load-bearing posts and even the overturning of the extension.

On what basis to install the extension frame

Before attaching a frame extension to the house, it is necessary to remove the turf and at least approximately determine the nature of the soil. The more clay, the stiffer and heavier the foundation of the extension frame should be.

Wooden buildings with a supporting frame are installed on following types foundation:

Pile-grillage;
Columnar;
Tape shallow.

Most suitable option foundation is determined by the degree of soil heaving in winter period and the rigidity of the walls of the house. For a frame extension to a wooden house small size you can use a columnar foundation.

IN ideal the wooden frame of a small extension is installed on the same foundation as the house, this avoids problems with shrinkage and temperature fluctuations. The light weight of the extension has virtually no effect on wooden walls main house.

It’s another matter if the room attached to the house has two floors, and the dimensions of the frame are only slightly smaller frame base the house itself. In this case, the extension is installed on strip foundation made of brick or concrete, since the frame made of timber, even reinforced with struts, is not rigid enough.

Pile supports for the extension frame

The strip foundation goes well with the wooden frame of the extension on relatively stable sandy and rocky soils; if it is necessary to install the attached premises on clay or water-logged soils, then the only option for the foundation will be a pile-grillage foundation.

Thanks to the use of piles, two serious problems can be solved:

Avoid deformation of the frame, destruction of floor beams and strapping of racks due to soil heaving;
Reduce flow and absorption of ground moisture wooden structures frame. The strip foundation has always been considered the “wet” and coldest.

The use of screw piles allows you to assemble an extension of any size, to almost any house, be it brick, block or wooden structure. In this case, the frame extension to a wooden house turns out to be balanced in terms of horizontal loads, that is, when strong wind or soil pressure, the rigidity of the foundation is sufficient so as not to load the main building.

Piles can be screwed or poured in close proximity to the foundation of the building, since there are no deep trenches, and the supports are “softly” screwed into the ground, the risk of damaging the foundation of the house is minimized.

For small rooms the frame structure can be installed on cheaper asbestos-cement pipes in order to reliably tie the skeleton of future walls and floors to the supports, wire or anchor bolts are embedded in the pipe heads.

Strip foundation of the extension

The scheme for constructing a strip foundation for a room attached to a house is practically no different from a standard MZL foundation. The only difference is that the width of the tape is made quite thin, no more than the width of the strapping beam. It makes no sense to make it wider, since the concrete strip has a safety margin an order of magnitude greater than what is required to hold the extension frame. The foundation for a frame extension to a house is built with your own hands, photo, in two full working days

The foundation base must be covered with rolled waterproofing and covered with a strapping beam, to which vertical posts, struts or SIP panels will be attached.

Next comes the process of filling the subfloor with boards, insulation and waterproofing of the attached room is carried out at the final stage, and in the meantime, a panel of boards is laid for ease of assembling the frame of the extension. After assembly frame structure The logs will be laid on the strapping beam and then a decision will be made on how to cover the floor with boards or OSB boards.

We build the walls and roof of a frame room

The bottom frame beam is sewn to the pile or strip foundation using anchor bolts. First, the insertion is carried out at the corners of the extension and only after marking the installation points vertical racks are looking for free space for anchors.

External walls of the extension frame

The extension frame can be assembled in two ways. The first option involves the formation of external walls using a series of vertical posts made of timber, connected to each other by jumpers of their boards and scraps. The heads of the racks are necessarily connected by an upper frame beam, which will subsequently serve as the basis for the formation of the ceiling and roof of the extension. All elements of jumpers between posts, joints and mutual insertion wooden elements the frame must be reinforced with mounting metal plates.

The frame cells are filled with mineral wool mats, or covered with sheet EPS, after which a lath is filled to remove condensation and a film vapor barrier is laid. The internal and external surfaces of the frame walls are sheathed with OSB or clapboard.

Particular attention must be paid to the corner posts of the frame and the equestrian openings. Most often along the corner seam line in winter time Intensive freezing of condensate occurs due to the presence of a cold bridge. To internal corners the rooms were not damp; the frame was supplemented with a simple casing of two boards, stuffed onto slats.

The second option for forming a frame is used for the construction of extensions large sizes. Instead of forming the outer frame in the traditional cellular way, only the corner posts are built, the upper and lower frame beams are laid, and the walls of the extension are assembled from ready-made SIP panels. Next, the beams are sewn interfloor covering and ceiling. As a result, the main load is carried by several massive racks made of 150x200mm timber, while the walls and ceilings remain as if suspended.

Important! Regardless of the method of assembling the frame between the walls of the building and the attached premises, a expansion joint, which is filled with insulation and rubbed with silicone.

The joints and seams between the SIP panels are glued with acrylic paste, after which you can proceed to the construction of the roof frame.

Assembling the rafter system

To collect rafter frame The roof takes approximately half of the working time planned for the construction of the extension. The simplest option involves making gable roof coaxial with the roof of the main building. To make it easier to connect the two rafter systems the height of the extension is chosen 60-70cm lower than vertical size Houses. In this case, the roof simply rests against the gable of the house.

If an additional room was added to the side wall of the house, then the main axes of the rafter systems form parallel lines. To prevent a dead zone from forming between the slopes, the attached room is used pitched roof articulated by rafters with load-bearing elements at home, as in the diagram.

Most difficult option The joining of the frames of two rafter systems is shown in the photo.

Such joining options present a certain complexity even for experienced carpenters, so such roofs are usually ordered turnkey construction companies. The main problem is to ensure the tightness of the roof covering in the area where the ridge beam enters the rafter frame of the house. The wooden skeleton of the attached room will shrink within six months, as a result of which the abutment zone collapses and opens even when reinforced with metal aprons.

Conclusion

Frame technology for arranging an attached room allows you to build a box quickly enough and without unexpected costs for repairing the foundation or correcting the masonry. Today, frame houses and extensions are considered the most promising construction option, so many companies and organizations have begun producing ready-made attached premises with the possibility of pre-ordering and manufacturing up to 70% necessary components. Such a set will only need to be delivered to the site and assembled like a children's construction set.

Frame extension to the house

How to create a frame extension to a house, the reliability of the construction of the foundation, walls, floor and roof. Stages of work, tips for insulation. Types of extension.

Over time living area gets used to it and wants to expand it, for this case you will need a frame extension to the house, which will be an excellent solution. So that all the pitfalls do not cause problems, below we describe in detail what the extension is intended for. How to choose the right base, features of creating a tape and columnar foundation. What to choose for the floor: wood or concrete, how the walls and frame are erected. How reliable flooring and roofing occurs. What is the proper insulation of floors and walls?

What does it consist of technological feature extensions, what methods exist for installing a frame extension to wooden floor. Stages of construction frame house with your own hands. How to create a construction project, how to build additional living room, kitchen or bath, features of installing a veranda.

How to choose a frame extension to a wooden house, fastening to a wooden structure, the importance of finishing. What materials and tools are used, how the site is planned, how to choose flooring material: concrete or wood.

When various reasons If there is a need to expand the living space of a private house, then the most economical and technologically simple option is a frame extension. Its advantage is the speed of construction with your own hands with minimal skill in working with carpenter's tool. Step-by-step instructions for the construction stages will help you make useful and beautiful extension, which will last for many years.

To ensure that the extension does not subsequently have to be transformed, the design nuances should be considered even at the planning stage.

First, decide on the purpose of the new premises.

Additional room. Building an additional room is equivalent to building a small house. All structures of a new building must be thoroughly insulated, otherwise heating such a room will be ineffective due to large heat loss. You should not skimp on waterproofing and insulating the foundation, otherwise dampness and mold on the walls will make it impossible to live in such a room.
Kitchen or bathroom. Take care of the let down engineering communications before you start building the foundation. Places where water mains or sewer pipes through the foundation it is necessary to insulate well. This is easier and cheaper to do during the construction phase.
Veranda is a light extension to an open or glazed house. Used for summer holiday. The building is not heated, so the design is extremely simple: the flooring, walls and roof are on supports. Do not forget about harmony; the veranda must be combined with the house in scale, style and materials of construction.

Selecting the base

The veranda can be attached or built-in. If the second is planned at the stage of building a house, then a separate foundation will need to be built for the first. With a gap from the wall of about 40 mm. Otherwise, when shrinking monolithic base will be destroyed due to different weights verandas and houses. The seismicity of the soil and the weight of the future building are taken into account. A lightweight foundation built on soil prone to heaving will “lead” and the extension will move away from the house. Such a base is designed for light walls; shrinkage is inevitable under the weight of the brickwork.

For construction they use different materials: concrete, brick, stone, piles made of wood, metal or concrete.

It is important to choose the right depth and type of foundation for the extension:

tape;
slab;
columnar;
pile;
pile-grillage.

In private construction, when constructing a base for a veranda, a columnar or strip structure is most often used. Let's take a closer look at the step-by-step instructions for arranging foundations.

Strip foundation

For large and heavy buildings, a strip type of base is chosen. It is advisable to make it from concrete in this sequence.

Using string and pegs, markings are made along which the trench will be dug.
The soil is selected to the depth of the base of the house foundation. Sand is poured onto the bottom and compacted. A layer of crushed stone is laid on top, which is also compacted with a hand tamper.
Prepare formwork equal to the height of the future foundation. Waterproofing is laid inside along the perimeter and welded reinforcement is installed on the crushed stone layer.
Prepare a concrete solution in a ratio of 1:3:6 (cement, sand, crushed stone).
Poured ready mixture for 1/3 of the formwork. After hardening, fill the remaining height. The solution is compacted with a vibrator to remove air bubbles. Or tap the walls of the formwork with a hammer.
The upper part is leveled. Cover with film. While the solution gains strength, the surface is periodically wetted to prevent cracks from occurring.

Important. Before erecting walls, waterproofing must be applied to the foundation. Use roll materials or mastic.

Columnar foundation

For easy frame veranda It is appropriate to erect a columnar foundation, which is made of brick, rubble stone or concrete. Or combine these materials. The holes for the pillars are dug to a depth below freezing of the soil. The pitch between the pillars is about 60 cm.

Sequence of work:

dig square holes 50 x 50 cm. Sand is poured onto the bottom and compacted thoroughly;
lay a layer concrete mortar, and after complete setting, they begin to erect brick supports. Use a level to ensure that the masonry is strictly vertical;
a concrete support is made similarly to a strip foundation: it is wrapped inner part formwork waterproofed and inserted reinforced frame. The form is filled with concrete, and the top is leveled. Wet the concrete a couple of times a day to avoid cracking;
After complete drying, the formwork is removed, waterproofing is applied to the pillar, and the top is covered with several layers of roofing material - the material will protect wooden beam floors from getting wet;
the remaining voids are filled backfill: soil mixed with crushed stone is filled in; compaction is carried out every 15 cm of the layer.

Floor: wood or concrete

A concrete or concrete foundation is installed on a strip foundation. wooden floor. The base on pillars is obviously designed for arranging a wooden floor.

Let's consider both technologies:

Concrete. Inside the foundation, soil is selected to a depth of 35 cm. sand cushion, compact well. Then you can fill it with crushed stone, but expanded clay is used to insulate the screed. A 20 cm layer is enough. A reinforcement grid is laid on top. Using a level, beacons are placed, which are then used to fill cement screed. Lay tiles or wooden flooring on top.
The wooden floor is installed along the floor beams, which are laid on the base on top of the waterproofing. The beam is connected to the foundation with through fastenings, anchors or self-tapping screws. In the corners they are connected with a straight lock and additionally fixed with corners. Next, the logs are installed, insulation is laid and the flooring is laid.

Construction of frame and walls

Wall structures are erected from timber, attached to previously assembled crown beams. The wall elements are assembled on a flat area in a horizontal position, and then the finished wall panel is mounted in a vertical position or each beam is connected to a beam in series.

Step by step instructions:

On the lower beams of the harness, make a cut for vertical posts every 50 cm.
Mount the racks, securing them with corners and self-tapping screws.
Assemble the top harness.
The veranda is connected to the house by attaching a vertical beam to the wall.
Secure all posts adjacent to the house with anchor bolts.
It is better to immediately sheathe the finished “skeleton” of the veranda with outside plywood, boards or OSB. This will give the structure rigidity.
After constructing and insulating the roof, install windows and doors.

Ceiling and roofing

The shed type of roofing can be combined with almost any roof of the house, therefore it is the most common configuration. Let's consider it.

The rafters are installed at one end under the slope of the roof of the house, and at the other they are supported on the wall of the veranda. Fixed metal corners. The main thing is to accurately select the slope angle.
The rafter legs should protrude beyond the wall by at least 30 cm. Such an overhang of the roof will protect the walls of the veranda from precipitation.
The issue of roofing is decided in advance. Usually they choose the material with which the house is covered. Under soft roof laid on the rafters solid material: plywood, OSB sheets or frequent lathing. Slate or metal tiles are laid on the rafters if the logs are installed with small pitches.
The structure is covered with waterproofing, which is selected individually to the coating material.
Laying the roof begins from the bottom of the rafters.
Used for insulation mineral wool, which is laid between the rafters. The ceiling is covered with boards or panels and decorated.

Insulation of walls and floors

Mineral wool is used as insulation material for walls. The mats are easily and quickly laid between the frame bars, as can be seen in the photo. When laying insulation in several layers, the mats are shifted relative to each other to prevent heat loss through the joining seams.

The insulation is covered on both sides with steam and wind insulating material, which will protect the material from moisture accumulation, and the top is sheathed with finishing material.

Internal walls can be sheathed with chipboard, plasterboard and covered with wallpaper or lined with clapboard. For outer wall use wood, siding or materials that match the finish of the home.

Wall pie towards external wall looks like this:

internal lining;
vapor barrier;
insulation material;
windproofing;
external cladding.

Floors on wooden joists are insulated in the same way as walls: mineral wool is laid on the subfloor between the joists, having previously covered the boards waterproofing membrane. A second layer of waterproofing is laid on top of the insulation and then leveled with plywood. After this, the finished floor covering is installed.

A concrete floor can be insulated similarly to a wooden one, apply a dry screed, make concrete screed and install water or electric heating.

DIYers often overlook the need to comply with safety regulations. Use the funds personal protection and a well-functioning, reliable tool, and then you will have only the warmest memories from the construction of the extension.

Extension to the house – great solution to expand the free space in any type of home. It is important that all construction work can be completed independently.

Of course, this will require certain construction skills and knowledge of work technologies, but there is nothing particularly difficult about it. The help of specialists may be required at the design stage of the structure, as well as when connecting communications inside the structure. In addition, certain problems often arise when legitimizing an extension with regulatory authorities.

The attachment can perform a variety of functions.

Most often, an extension is built to form an additional room, summer kitchen, garage, veranda, terrace, canopy, porch. There are a huge number of options - everything will depend on personal requirements and wishes. Of course, building something will be very difficult from a technological point of view, but often all construction is done with your own hands.

The main thing here is to correctly construct the foundation, walls, roof, insulate and isolate the room from moisture, and also correctly attach the new foundation to the old one.

Types of extensions for country houses

Before starting any construction work, it is necessary to clearly determine the type of construction, because making an extension to the house is possible only if you have a clear plan and project. There are several most common types of extensions in our country:

Canopy

This is the simplest and most cost-effective extension for country house. The main functional task of such a design is to protect people and things located under the canopy from sun rays, rain and other precipitation. It will be good to relax under such a canopy warm time year and have lunch, or you can park the car.

Carport.

An important advantage of installing a canopy is that the construction of a foundation is not required, because the foundation will be support pillars(made of metal, wood, concrete). The canopy frame is attached to these supports.

Summer room

To form a summer room you will need more capital construction than in the case of a canopy. Such rooms are intended for relaxation in the warm season, gatherings, reading books, etc. Naturally, a foundation will be required.

It is recommended to use columnar or strip base, depending on the type of building material and the dimensions of the room. Boards are usually used to create walls, foam concrete blocks, frame panels. For better lighting walls and roof, wholly or partially, can be made of glass.

Summer room.

Such an extension usually has a lean-to or gable roof. It is recommended to use the lightest roofing material. Installation thermal insulation materials, as a rule, is not carried out, because such premises are not used during the cold season.

Living room

Before adding a room to the house, it is necessary to complete all the required calculations and draw up a project. In this case, a thorough approach will be required, involving the construction of a foundation, capital construction of walls and roofs, installation of waterproofing and thermal insulation materials, and supply of all necessary communications.

Warm living room.

Particular attention is paid to insulating the premises, so that one could live here in winter without spending a lot of energy on heating.

Kitchen

As a rule, extensions are not intended to accommodate a kitchen. Such a structure must be capital, so it needs to be insulated as efficiently as possible.

Kitchen made of wood.

Correctly building such an extension can only be done using quality project, created by professionals, because the kitchen needs all communications: sewerage, water supply, electricity, gas, ventilation system. This, of course, leads to serious financial costs, for which not everyone is ready.

Garage

Using an extension to create a garage is a very common trend in recent years. The garage will require the construction of a strip or monolithic foundation, and for the construction of walls, foam concrete blocks or bricks are usually used.

Two garages.

The roof, in most cases, is made of profiled sheets or metal tiles, slate or roofing felt. Mandatory communications for the garage - ventilation system and heating.

Connection of an extension with a country house

Many people spend a long time choosing where to add a new room to their home to make it easier to connect it with the main building. Here you have to choose from two options:

Independent building. In the event that difficult ground conditions are observed in the area (for example, heaving soils or high level groundwater), then it is recommended to build an independent structure that will not be connected in any way to the main house. In this case, the extension and the main structure have no points of contact, so they do not depend on each other. At the same time, between two buildings a minimum of possible distance, which is a technological gap that must be filled with thermal insulation and waterproofing materials.
Implementation of an extension to the structure of an old building. Such a solution involves a certain amount of labor, because construction will require compliance with all necessary technologies and carrying out many calculations and studies. First of all, you will need to properly build and insulate the foundation, which must be correctly connected to the base of the country house. This is usually done using reinforced rods. Using approximately the same technology, the walls and roof of structures are connected.

Features of roof construction for an extension to a house

The roof of an extension to a house can have any shape - here again everything will depend on the requirements and wishes of the owners. At the same time, most often country homeowners choose pitched roof, because it is simple to implement, easy to insulate yourself, it fits well with other types of roofs that the main structure may have, and also removes precipitation well, preventing the entire structure from experiencing additional loads.

In order for precipitation to drain normally from the roof of the extension, the design of the roof involves installing a roof slope of 20 degrees or more.

Besides, special attention It is necessary to pay attention to the establishment of the roof of the extension under the roof of a country house. If everything is done correctly, the wall located between the extension and the country house will be protected from water entering through the joint between the two structures. In addition, the roof of the extension must be extremely harmoniously combined with the roofing material of the main building and fit harmoniously into the exterior of the building, without standing out from the general background.

During the design process, it is very important to correctly calculate the load that the roof structure will provide. The weight of the rafters should be taken into account, roofing material and others structural elements, used in roof construction.

It is important to understand that the extension to the house is screw piles or pillars is not designed for too heavy loads, unlike monolithic or strip concrete foundation. You also need to insulate the roof (you can insulate it using any suitable thermal insulation materials, which it is recommended to cover the top with waterproofing).

How to legalize construction?

Build an extension to the old or new one country house- that's half the battle. Any additional premises erected on a land plot must be documented and obtain permission to carry out construction work from regulatory authorities.

An extension to the house can be done with your own hands; no one will force you to invite builders, but the homeowner must submit a well-drawn design of the structure to the employees of the regulatory services.

The procedure for completing all the documentation for an extension to an old country house usually takes from several months to a year.

An interesting point is that you can start collecting documents and obtaining a building permit after all the work is completed. This is permitted by current law.

At the same time, when reviewing documents, employees of the regulatory body may have some claims that will have to be mandatory correct (for example, the location of the building relative to underground communications or use of unsuitable building materials).

Let's consider buildings to the house and not extensions

A pergola is the simplest structure and an excellent place to relax.

A barbecue is a great place for entertaining guests and celebrating.

If the owner personal plot decided that he needed an extension to brick house, the first thing you need to do is decide on the purpose of this design. If it will be used for recreation, it can be built in the format of a gazebo or terrace. If necessary, the veranda can be insulated and turned into a closed terrace, which will serve as a vestibule between land plot and the entrance to the house. This will prevent cold air from entering the living space. For those who live in a house during the autumn-winter period, an insulated extension will be an ideal option.

The extension can serve as a porch, terrace, as well as a kind of vestibule for a brick house.

Before starting construction, the extension to the house must be designed and approved by the relevant organization. Most often, the veranda is built from the side front door. If it is not combined with the entrance to the house, then you will have to enter it from the street. The dimensions of the structure are selected depending on the number of people living in the house. For a small family, an area of 12 sq.m. is sufficient. When designing, it is necessary to take into account general style house and plot. Before making an extension to a brick house, you need to complete some formalities. Once the design has been thought out, you should contact the building design department. Here you can order finished project with whom you will go to the city architectural bureau obtain permission to redevelop the house. Let's take a closer look at how to make an extension to your house with your own hands.

The first step is to mark the area and begin building the foundation.

It is quite possible to make an extension to a brick house correctly with your own hands. You need to start by marking the territory. To do this, remove fertile layer soil, which will later be used to form flower beds and flower beds. The territory is leveled and marked.

The boundaries of the extension are designated according to the project. At the corners of the veranda under construction, pegs are driven in with a nylon cord stretched between them. Any building requires a reliable foundation, for which you can choose a columnar or strip foundation. It is not recommended to combine the foundation for an extension with the base of the house, since these structures have different degrees of shrinkage.

A distance of 4-5 cm must be left between the base of the house and the extension. When constructing the base, the planned mass of the structure and the characteristics of the soil should be taken into account. When building on heaving soils, the foundation may shift, which leads to the separation of the veranda from the walls of the house. Lightweight foundations cannot support the weight of brick walls, so it is not recommended to build a brick extension on their basis. It is best to choose a strip foundation for an extension.

Before pouring concrete for the foundation, a trench is dug, the dimensions of which depend on the parameters of the veranda being built. They lay it in a hole wooden formwork appropriate design, which is made from boards knocked together. Concrete is prepared from 3 parts sand, 1 part cement, 6 parts crushed stone. The foundation for the extension is poured in layers, the first layer is reinforced with large stones. Top layer smooth with a trowel and leave until completely hardened.

At high temperature air, the foundation for the extension is periodically moistened with water, this will help avoid the appearance of cracks.

A frame extension to a brick house can be installed on columnar base. In order to avoid deformation of the building under the influence of soil heaving, foundation supports are laid at a depth below the frost line.

During construction brick extension support pillars are dug in not only at the corners, but also along the perimeter of the structure in increments of 50 cm.

Building the walls of the extension

In construction you will need the following materials and tools:

brick;
cement;
sand;
crushed stone;
fittings;
shovel;
container for preparing the solution;
trowel;
wooden beams;
thermal insulation material;
roofing material.

If you want to quickly build a veranda, you can opt for a frame structure. It is assembled according to the principle of a designer and consists of a wooden frame and ready-made panels with windows and doorways. Finishing work can be carried out immediately after construction. If necessary, the extension can be redone. Now let's look at how to properly make an extension to a brick building.

A brick extension to a house is more difficult to construct, but you can still build it with your own hands. Before starting construction of walls, you need to check the evenness of the foundation surface. If it's uneven, brickwork may collapse during shrinkage. Linking the extension to brick wall building is carried out using holes that are made every 3 brick rows. They contain reinforcement. During construction brick extension to the house, the reinforcement will remain in the masonry joints. To ensure that the distance between the bricks is not too large, the reinforcing bars should not have a diameter that is too large.

Before forming the brickwork, a rope is pulled along the wall, with which the horizontality of the rows will be checked. The thickness of the wall depends on the purpose of the brick extension. If the veranda is residential, the wall is laid out 2 bricks thick. For utility rooms brickwork can be done in 1 row. After the walls are built, their upper parts are strengthened concrete belt. To do this, formwork is made, into which a reinforcement frame is laid and concrete is poured. After the concrete has hardened, construction of the floors begins. A garage is attached to the house using the same technology; its dimensions depend on the dimensions vehicles. A wooden extension is more economical option arrangement of the veranda.

How to make an extension roof

In the final stages it is being built ceiling, for this purpose they use wooden beams. They are installed on the upper parts of the walls in increments of 70 cm. The structural elements are fixed with construction corners.

beams can be combined with a concrete belt, having waterproofed each element in advance. Thick plywood or wooden boards, which are then insulated. An extension to a house can have any roof shape. Most often, single-pitch options are made, consisting of rafters. A mark is made on the wall in the form of a straight line along which the bars supporting the rafters will be fixed. The rafters are supported by floor beams or the tops of walls. The rafters should protrude 30 cm from the walls to protect them from rain and melt water. The roof elements are fixed using metal corners.

As a conclusion

The quality of the extension depends on the chosen project and materials. An extension to a wooden house or brick cottage can be made of prefabricated panels, wood or brick. Anyone with minimal knowledge in the field of construction can build it with their own hands. The foundation for the extension can be strip or columnar.

Any of these bases requires high-quality waterproofing.

There are many options for assembling frame extensions to a house. The most economical and technologically simplest option is to assemble a frame structure. Such an extension will look best next to a wooden house. What materials and tools are needed for self-installation extensions and how is the technology for installing the structure carried out?

Technological features of extensions

The definition itself makes it clear that the basis of the structure is the supporting skeleton - a frame made of edged timber. Other parts of the building are also made from timber - the lower frame and corner posts. Conventional racks and lintels are made from simple boards. Also, with the help of boards, future doors and window openings in the room are indicated. The thickness of the racks should be equal to the thickness of the heat-insulating layer, and based on the width of the insulation, the pitch between the racks is determined.

Let's give an example: if the house is located in the northern part of the country, then the thickness of the insulation should be at least 15 cm. It follows from this that the width of the lumber should be 150 mm by 100 or 150 mm. The step size must be kept within 60 cm, since the width of the insulation board is 60 cm.

After assembling the frame structure, it is mounted. Do not forget that before this, hydro- and vapor barrier is carried out. After insulation works The rough cladding of the structure is carried out using OSB or DSP sheets.
