Corner extension to a wooden house. Extension to the house - the most interesting projects and the main types of extensions (130 photos). Verandas are the easiest way to expand your home
Very often, you want to add a veranda or terrace to a finished house in order to increase the available living space and simply transform the look of a residential facility. In such cases, an extension is built to wooden house, projects of which can be very different depending on the size of the new object and the materials from which it will be built.
An extension to a wooden house of a veranda and a terrace can be built different ways from point of view design features. Most often this is done in several ways:
- The extension is built on the side and has a single roof with the house.
- The extension is located on the side, but under a separate roof.
- The veranda is located on the second and higher floor or in the attic.
Of course, most often the extension is done on the side of the house. The option with a common roof is more convenient and profitable, but for this it is important that you can make a roofing system common with the house. As for the add-on, this process is not an easy one. So, first of all, it is important to take into account the possibilities of the foundation of the house, which may simply not withstand the load under the influence of the built-on terrace.
What material to choose
An extension of the veranda to a wooden house can be built using different materials. Most often it is timber, log or frame technology, as these options look harmoniously against the background of the general exterior of the cottage. But extensions made of brick or foam blocks are no less popular. We note right away that each of the options has its own nuances in terms of construction. Consider the features of the construction of each material in more detail.
Timber extension
- the most common material. This is due to the characteristics of the material itself:- Its production is carried out in the factory, so the wood is of high quality.
- Thanks to special processing material possesses high resistance to rotting, a fungus.
- Environmental friendliness and naturalness are the main advantages of a bar of any variety.
But before you make an extension, you need to solve a number of questions for yourself. The most important is the foundation of the future home. There are a huge number of options for its creation, but any foundation must be firmly “tied” to an existing building. Ideally, the extension needs the same foundation as the house. Therefore, it is important to study the condition of the soil, its type, to think about what the load from the extension will be. After that, the second issue needs to be resolved: the veranda will be combined with the common perimeter of the house or will be built as a separate structure. It is not easy to combine structures, since it will shrink, and even specialists will not answer what it will be.
Frame extension
From the frame is a budget option, since significant investments in its construction are not required. In addition, the very construction of a veranda or terrace will be much faster with minimal spending on materials. The construction of the structure is carried out on the basis of a frame consisting of a wooden bar or metal profiles. The frame is being built around the entire perimeter of the future veranda.
After the frame is ready, you can start decorating the walls from the outside and inside. For this, chipboard or OSB boards are used, and between them a laying of insulating material is required - mineral wool, sawdust, polystyrene foam. A more time-consuming process is a brick extension to a wooden house with your own hands. The solidity and durability of the future home, already together with the veranda or terrace, can be ensured if you follow a few rules: An extension of foam blocks to a wooden house is in great demand for several reasons: The only negative is the need to protect the material from the effects of factors environment. For these purposes, foam blocks are often finished with siding or bricked. Before you build a terrace or veranda, you must first determine their location in relation to the house. For example, for cozy breakfasts on the terrace, it is better to place it on the east side, as there will be more sun in the morning. And if, on the contrary, you need a shadow, you should look for the most shaded place on the site. Dimensions need to be thought out so that the extension looks harmonious against the background of the overall design. The foundation for the veranda needs to be well thought out. Depending on the materials from which it will be built, the base can be simply in the form of compacted soil, or it can be built of concrete. It can be erected from foundation blocks and slabs, corner posts, which are fixed in the ground and carefully concreted. The foundation necessarily requires waterproofing using, for example, hot bitumen, cold mastic. At the very last stage, backfilling of the base is performed.
from brick
Decide on location and size
Second: foundation
To make your home comfortable optimal solution is to create additional space. First of all, projects for extensions to a wooden house and any other must be properly legally executed.
It is better to do this in advance, since it is easier to make changes to them than to redo an already finished design later.
The purpose of building an extension
- Arrangement or porch.
- Creation of a technical room (workshop, garage, boiler room, electrical panel room, pantry).
- Expansion of living space (living room, bathroom, kitchen, dining room, hallway).
It should be borne in mind that the extension has some features compared to other structures.
What extensions are suitable for a wooden house?
Despite the functional difference of the additional premises, there is a prerequisite - ensuring the safety of the main building. For wooden houses the use of extensions from identical material is advisable in order to create harmony and prevent overloading the foundation. If the main building is a log house, logs, timber and even aerated concrete blocks. But wooden extensions remain preferred.
The most rational option is to attach frame structure. Availability modern materials makes it possible to make new premises as comfortable and functional as possible all year round.
What should be considered when creating an extension?
The following factors must be taken into account in construction:
- and its dimensions.
- The condition of the walls with the roof and what elements need to be replaced.
- The possibility of rigid connection of structures and the creation of a transition between rooms.
- transitions between rooms.
Due to the fact that a wooden extension shrinks during the first year after construction, it is not recommended to do it rigidly to the walls of the house. Between them leave the so-called providing relative slippage of the walls vertically. It is necessary even when common ground and separates all parts of the building from the bottom up, up to the roof. Finally, the seam is filled with elastic tapes, polystyrene foam, plastic mass made of bitumen, silicone or acrylic.
When combining different materials at the junction, embedded elements are used: reinforcement, channel, corner. The tightness of the joint is created using a gap of 1-2 cm, which is subsequently filled with mounting foam and closed with a flashing. Metal should be carefully painted to protect against corrosion.
It is quite possible to create a basement under a new room. In this case, it is necessary strip foundation deep laying. But it is impossible to lay a new foundation below the sole of the old one. The sole of the foundation of the extension should be the same as that of the house, or placed higher.
Project work
The projects of extensions to a wooden house have become the most popular due to their economy, simplicity and efficiency. First of all, a project is created. The extension complements the house, creating a single whole, and is not a separate part of it. It is important to provide for the condition of the adjoining walls and, if necessary, replace the rotten parts.
One style should be followed. The dimensions of the additional building should not exceed 2/3 of the house. In this case, it must be taken into account that the general appearance of the facade is not disturbed. The area of the veranda is usually about 20% of the house.
The extension can be two-story. It is important to ensure its reliable thermal insulation. If the attached room is combined with the rooms of the house doorways, it must be securely insulated. Otherwise, it will affect the microclimate of the whole house. Protection from the cold must be provided on all sides.
When changing a residential building, permission from the city architectural committee is required. All necessary drawings are being prepared. Service price construction company, which is taken to create an extension project to a private house, ranges from 25,000 r. Suitable option You can choose from the suggested photos.
Typical finished projects it is difficult to apply, since it needs to be tied to the existing structure of the house and the state of the soil. They are taken as a basis, making changes of different levels of complexity, depending on the wishes of customers. As a result, an original solution can be obtained.
Building a new foundation
When projects are being developed for extensions to a wooden house, special attention is paid to the foundation. So that it does not shrink, it is connected to the base of the house. You won't be able to get a monolith, but you can get close to it. First, a trench is dug and the attached parts of the main foundation are released. The waterproofing is cleaned from it, and then recesses are drilled to a depth of 60-80 mm with a crown with a diameter of at least 100 mm. After that, instead of the crown, a drill is inserted and thin holes are drilled in the concrete. Then reinforcement is hammered into them. The frame of the new foundation is attached to it and it is poured with concrete. After hardening, waterproofing is laid on the base, after which it is possible to build an extension from any material, but it is not recommended to create heavy structures.
If the reinforcement of the two foundations is not done, over time they may disperse.
How to make a roof
The roof of the extension is erected separately. It is made single-sided and with a large slope. There is no connection to the main building. In this case, it is necessary to ensure a tight fit of the roof to the wall of the house. Then its subsidence will not occur in the process of shrinkage and shrinkage of the structure.
The roof is located below the main one or is made with it as one piece. It should be ensured that the shrinkage of the new structure does not lead to subsidence of the roof. If a decision is made to build a common roof, then the entire roof will have to be reconstructed.
Construction of an extension from a bar
Projects of extensions to a wooden house most often involve the manufacture of new structures from the same material, for example, from a bar. The building is usually attached to the facade wall and may have as many floors as the house has. Then the foundation is made the same, and the roof can be common or one-sided pitched. Under the veranda, a lightweight columnar base is used.
The walls are built using the same technology as for the main house. The beam is connected to each other with dowels. Fastening to the main wall is made with plates with screws or brackets.
An extension made of timber is usually intended for residential premises.
For her, the roof can be made common by connecting the floors with metal corners. The design of the drainage system is made integral.
Add-on costs are as follows:
- type of construction and decoration;
- number of floors;
- the complexity of the foundation;
- availability of communications;
- type of beam.
The general list also includes the price of the project, transportation and the complexity of construction.
Frame extension
The frame base is the simplest and most common solution for building an extension to a wooden house. Despite the fact that this technology has appeared recently, it has received universal recognition due to its economy and speed of construction.
The frame is made of wood or metal. The cost of a structure depends primarily on its purpose. Most high costs requires the construction of a dwelling where insulation is required with mineral wool, polystyrene foam, polyurethane foam and other heat-shielding materials.
Metal structures are made of profiles different shapes and dimensions by welding. Cheaper wooden frame also differs in durability and durability.
The foundation is made small and can be shallow or columnar. It is displayed on a par with the main one at the top level.
The wooden frame is treated with an antiseptic and fire-fighting composition. Then it is assembled. From the side of the facade, the walls are sheathed with sheets of plywood or OSB, with siding or plastic trim, and from the inside - clapboard. If it is pre-coated with several layers of varnish, the service life of the material will be significantly extended. Insulation is placed between the outer and inner lining.
Attaching the porch to the frame structure is not difficult. A small foundation is made under it, connected with the main one.
Conclusion
An extension to the house allows you to increase living space and create comfortable living conditions at minimal cost. This can be done with your own hands, if you correctly develop your own or make changes to finished projects with reference to specific conditions. At the same time, mistakes in construction should not be made.
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 to be expanded, then an extension is an ideal option to increase the 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.
Room attic type will be more expensive, since it is supposed to perform 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 use a sandwich:
- 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 over the reinforcing mesh with a 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.
As an option, you can disassemble roofing cake but do not dismantle the rafters. For a new building, a shed roof is being erected. Enhance truss system can be racks.
No matter how big your a private house, sometimes it is required to attach another room to it. The purpose of the new room can be different: inside they equip a bedroom, a pantry, Gym, veranda, dining room, even a bath or garage. The best option in this case - an extension to the house from the frame. The structure is placed on the foundation, a kind of frame “skeleton” is made, on which the walls of OSB-plates, insulation and waterproofing are “put on”. The extension to the house is equipped with a floor and a separate roof, sometimes windows and always a door.
Before starting the construction of a frame extension to the house, decide on its location. On the north or east side, it is advisable to place a pantry or utility room, on the south or west - a bedroom or living room (then there will be a lot of light in the room, during the day the sun will warm the frame extension, so you will save on heating).
If the extension will have a bedroom or living room, then make it on the south side - so you can save a little on heating
Now sketch out a house plan with a new room on a piece of paper, indicate exact dimensions buildings and materials that will be used in the construction.
This plan must be submitted to the technical inventory bureau of your locality. Of course, not all homeowners run to the BTI in order to organize a frame extension. But in vain! If checked, the illegal building will most likely be ordered to be demolished. Do you need such problems?
As practice shows, BTI specialists will not create obstacles and will quickly approve the project (maximum within 10 working days).
Permission from the BTI for an extension to the house will be issued within 10 days. Provided that the application meets all the established requirements, and the construction meets the technical standards
Tools and materials for creating a frame extension to the house
Permission from BTI received. Now you need to prepare tools and materials for construction. You will need:
- cement mortar;
- wooden planks;
- sand;
- small pebbles;
- OSB boards;
- insulation;
- waterproofing;
- putty;
- paint for OSB-plates;
- roofing material;
- wooden or steel door(at the request of the owner);
- window in plastic or wooden frame(if necessary);
- linoleum, ceramic plates or laminate flooring;
- perforator;
- construction mixer;
- rollers and brushes;
- nails and screws;
- mounting foam;
- construction stapler;
- shovel;
- metal pipes diameter 15-20 cm, length 2.7-3 m.
Cement mortar is sold in packages of 25 kilograms each. Terms of use are indicated on the product packaging. Price - 700 to 2 thousand rubles, one of the best manufacturers- "Silka", "Maxsil", "Mapey".
The base of the extension must be strong and stable, so choose quality cement for the foundation, not a cheap mixture
Wooden boards will be needed first to create the foundation formwork. Then they can be covered with a cement-filled floor to insulate and soften it. For such purposes, spruce, pine, oak are best suited. The thickness of the board is at least 5 millimeters. Choose the length depending on the area of \u200b\u200bthe frame extension to the house.
Choose OSB with a thickness of at least 7 millimeters with dimensions of 100 × 100 centimeters. The plate itself should be smooth and uniform. This speaks of high quality products.
How can insulation be used? mineral wool or styrofoam. The first option is cheap, but the material quickly becomes unusable. Expanded polystyrene has a long service life (up to 20 years). It is sold in the form of plates, the dimensions of one are 200 × 100 centimeters.
Choose products from 10 millimeters thick from the companies: Penoplex, Extrol, TechnoNikol.
Expanded polystyrene for warming an extension to the house is preferable to mineral wool. It does not absorb liquid, is not afraid of temperature changes
Waterproofing is a must. As such, you can use a polymer roll material. Thickness - at least 5 millimeters.
Price per square meter- about 500 rubles. Among firms, users recommend giving preference to the following: Bolars, Penetron, Polylen, Zubr.
Putty and paint are needed for exterior and interior decoration. You can learn more about the choice of paint.
On the roof you can put a metal tile. It is a durable and weather-resistant material that will last a long time, besides, it looks stylish and is inexpensive.
For a square meter you will pay 200-400 rubles. The thickness of the tile must be at least 5 millimeters.
Important: the easiest way is to create a frame extension to the house using OSB. Such a room will be warm and durable if it is properly insulated. Of course, walls can be built from bricks, foam blocks or wooden beams. But it is much more expensive and energy-intensive.
The drawings below will help determine the type of room:
With the help of such a drawing, you can create a simple extension to the house with pitched roof. Use your own sizes
Such a drawing of an extension to the house will help to simply and quickly build an additional room or, for example, a pantry.
By stages: stages of building construction
The process of erecting a frame extension to a wooden house can be divided into several stages:
- building a foundation;
- floor filling;
- erection of a frame for an extension;
- wall production;
- roof laying;
- installation of windows, doors;
- exterior finish;
- interior decoration.
Work must be carried out consistently, following the instructions and safety precautions. For some "activities" (installing windows, laying the roof), it is advisable to involve an assistant.
Strong foundation: pour the foundation
To create a frame extension to the house, it is necessary to fill in the strip foundation. But if on the site high level ground water, then it is more correct to make a pile or columnar foundation.
The instructions for erecting a strip foundation are as follows:
- Mark up and dig a trench 30 centimeters deep and 20 cm wide. The result should be a rectangle or square.
- Fill the trench first with sand, then with stones exactly half for strength.
- Insert metal pipes at the corners of the trench. They will serve as the basis for the future frame.
- Build the formwork for the foundation from the boards and fill the trench cement mortar prepared strictly according to the instructions.
- Leave the design for 24 hours until completely dry.
- Then fill the floor with cement mortar. It will dry completely in a day or two, depending on weather conditions. The warmer it is outside, the faster the cement hardens.
You will learn how to make a strip foundation from the video.
If you need columnar or pile foundation watch the following videos. They will talk about the rules for the construction of such foundations.
Strong "skeleton": we put the frame
The future building already has iron pipes in the corners. Between them, horizontally from the floor to the end of the pipe, other metal pipes are welded. The distance between parallel parts is at least 70 centimeters. You can “connect” the corner iron parts to each other using wooden boards. They will also serve as a frame.
Important: if the distance between the corner tubes is more than 1 meter, then in the middle you can put another vertical pipe or board to give the frame strength and reliability.
How to make a frame for an extension to the house, see the video.
Construction "sandwich": building walls
Now, in the process of building an extension from a frame to a wooden house, the most difficult and interesting thing begins with your own hands: the construction of walls. One camp is already there - it is part of the house. There are three more to do:
- attach the OSB to the frame with nails. Between them there should not be large gaps of more than 3 millimeters.
- On the inside of the OSB-plate, fix the waterproofing with a construction stapler. The material should cover the entire area of \u200b\u200bthe walls - from top to bottom.
- Attach the insulation to the waterproofing with polyurethane foam. The work is not difficult. It is quite possible to deal with it alone. Do not apply too thick a layer of foam and press the insulation board firmly against the OSB wall.
- Place OSB boards on the insulation. Attach them with screws.
- Attach waterproofing to the existing wall of the house, and OSB on top.
- If there are gaps between the plates themselves or the floor, fill them with mounting foam.
Builders call this construction a “sandwich”. It is built quickly and simply, but practical in operation, reliable and durable.
If you need to install windows and doors, consider them before you start installing the walls. In OSB-plates, it will be necessary to pre-cut holes of the desired size.
You will learn more about the plates themselves from the video:
Serious protection: without a roof - nothing
The roof for a frame extension to the house can be made shed or. In any case, its creation involves the following steps:
- We build a base from wooden boards.
- We put a heater on top.
- We put waterproofing on the insulation.
- From above we fasten the metal tile with an overlap. In this case, moisture from precipitation will not accumulate under the tiles.
The shed roof of the extension to the house, as it were, continues the existing roof. It's pretty easy to build. It is enough to put wooden slats of the desired length on the main roof
To be beautiful: interior and exterior decoration
The construction of the frame extension to the house is not completed until the interior and exterior decoration has been completed.
The best option for OSB boards is painting.
First prepare the surface:
- sanding is performed;
- antiseptics are applied good quality at "Tixo", "Drevolak");
- primer treatment ("Body", "Tex").
Then the board is painted. Use alkyd, oil, water-based, acrylic, latex paints. For external and internal works different products are used. Information on which surfaces a particular dye can be used is indicated on the packaging.
You can find out more about painting OSB.
TO interior decoration include floor treatment. On cement screed put waterproofing, then insulation and wooden boards (this step can be skipped if you put laminate, linoleum or ceramic tiles on the insulation).
What's next?
It would seem that the frame extension to the house is ready. But putting it into operation is not yet possible - first you need to conduct electrical wiring in the room, install heating radiators and connect them to the common heating system of a private house.
You will learn how to wire.
Read about the heating system.
To make it cozy in the extension to the house at any time of the year, run the wiring inside, install heating radiators
Finally
In order for the frame extension to the house to be strong and safe, strictly follow the basic rules when building private houses in general and creating extensions in particular. Do not forget about the basic safety requirements at the construction site. Protect your hands and eyes, work in special clothing and sturdy shoes.
The easiest option for creating an extension from a frame for a house is OSB-plate. It is quite light, but fully copes with its "professional duties".
There is an opinion that using OSB is unsafe for health - products are impregnated with a mixture of phenol for strength. However, when painting and priming, phenol is stopped and not released, so OSB does not harm health.
