Who doesn't dream of spacious housing? Even the owners of large houses often wish to have even larger properties, let alone the inhabitants of small dwellings, which really do not have enough space. Construction of an extension to an already operated house perfectly solves this problem. The fastest and most budgetary option is wooden frame-based extensions. They are appreciated for the efficiency of construction, as well as for convenience and comfort.
They are especially suitable for houses built of various types of wood or foam blocks.
Such structures are successfully combined with any type of dwelling. Thanks to uncomplicated and original technology, you can expand your home. Such actions are usually taken to equip another room, utility room, to expand the kitchen or a large comfortable bathroom. Or maybe it will be a wonderful roomy veranda, where the whole family can gather so comfortably?
Already from the name of the frame extension it becomes clear that an indispensable element of the structure that serves as its basis is a frame made of edged timber. Other important parts of the structure are made from the same building material - corner posts and lower strapping.
Simple lintels and posts are made from ordinary boards. They are also used to outline future windows and extension doors. The thickness of the uprights and the insulation layer must be equal. The step width between the individual posts depends on the width of the insulation.
For example, if we are building an extension to a wooden house in the north of the country, it is recommended that insulation is not thinner than 15 cm.
This means that the estimated size of lumber should be 0.15 m by 0.15 or 0.10 m. The step is equal about 0.
6 m, since the insulation board has a thickness of 0.6 m.
An extension to a house made of a bar of a living room resembles the actual construction of a typical residential building, only of reduced size. This is due to the fact that in the course of work, reliable insulation and high-quality waterproofing of all walls and surfaces of the room will also be required. This applies to floors, ceilings and walls.
The foundation must also be solid to prevent the appearance of fungus, mold and dampness in the new room.
What is the difference between the veranda extension to the house? When erecting it, a door and windows may not always be required. Often, the frame for it is completely open, which is not an effective protection from strong wind, rain and bright sun.
Such a structure looks like a simple wooden frame, equipped with a flooring. Along its perimeter there are columns and half-walls, by means of which the roof is attached and held.
But verandas are different: the frame of some is equipped with solid reliable walls, a doorway and a window.
In any case, the foundation of the extension must be well waterproofed.This is the only way to avoid unpleasant dampness and humidity inside. If the owners prefer the winter version of the veranda, then the frame extension erected with their own hands should be thoroughly insulated. Good waterproofing of the new building is also required.
Kitchen or bathroom
The comfortable extension of the bathroom and kitchen, due to the frame extension to the wooden house, deserves special attention. It differs from others in that here, most likely, not only the heating system, but also the water supply and sewer systems will have to be operated.
Particular attention should be paid to proper waterproofing and quality wall insulation. The choice of the foundation should also be approached with all responsibility.
For arranging the strip foundation during the construction of a frame extension to the house, a number of necessary actions must be taken in the selected place:
Its size depends on how deep the foundation will be in the ground. The width of the pit should be about 15 cm greater than the thickness of the future wall;
A well-spread film is fixed along the walls;
Bituminous mastic, roofing felt or liquid rubber in the construction of extensions to the house are used as a water-repellent material.
For arranging the floor surface, inside the foundation, you can make a concrete screed and expanded clay pillow.
Another way is to mount a frame from logs and floor beams, on the basis of which a wooden floor is subsequently made. Its final finishing will be carried out after the final erection of the walls and installation of the roof.
Consider the production technology of frame-frame type walls. This will require:
Marking is made on the wall of the main building: it must be strictly vertical. According to it, separate beams and solid frame elements will be fixed.
A horizontal beam is securely attached to the main load-bearing wall by means of steel corners or anchors.
If you plan to erect a frame extension to the house, then you have to master the following work:
The beams are fixed to the foundation with special studs mounted in a load-bearing concrete base. Another method of fastening is with anchor bolts. For them, holes are made in the concrete in advance;
Then the foundation is equipped with a base floor;
You can use the same technology as in the production of the initial layer from a wooden beam;
All work is carried out using a plumb line and a building level.
After framed the extension is attached to a wooden or brick house, they proceed to the arrangement of the ceiling overlap. For this, the beams are fixed with metal corners on the surface of the walls made, at a distance of 0.6-0.7 m from each other. Then the beams are sheathed with boards or plywood.
Later, a layer of thermal insulation will lay on them.
There are different technologies for equipping roofs. Those who want to make a frame extension often prefer the version of a pitched roof. A similar structure is made of rafters, while it is important to choose the right angle slope correctly.
The slope of the corner can be 25-300: having marked it, a horizontal line is drawn on the surface of the main wall.
A bar is fixed along this line, which will become the support of the upper part of the rafter. And the end of the wall, or beams from an already made frame ceiling, will become the lower support of the rafter. It should protrude about 30 cm beyond the lower support - this will prevent precipitation from falling on the walls of the building. For the installation of rafters, galvanized steel corners are used.
A more complex option for attaching the frame extension by hand is possible: in the video you can find an option in which the roof slope of the main house is directed towards the erected extension.
In this case, the extension beam will simply have nothing to fix it on. We'll have to remove a part of the roof from the lower roof row, and only after that use the bare beams in the work.
If flexible shingles are chosen to cover the roof of a new structure, plywood sheets or frequent lathing are completely laid on the rafters. Waterproofing is also required. If the selected roof is large sheets, then the actual rafter system is suitable for them.
Waterproofing is mounted on it, then the roofing sheets themselves are overlapped (and fixed with fasteners).
Then they begin to insulate the walls and floor inside the extension itself. Mineral wool is very good for insulation. It fits inside the frame structure, between the beams. On top of it, with brackets, a special vapor barrier film is mounted on the bars.
When erecting a frame extension from our step-by-step instructions, it clearly shows the sequence of actions . At the final stage, at the very end of the work, the walls are finished with OSB plates, plywood or drywall. If you follow all the technology, use the right materials, then a self-made frame extension will faithfully serve the owner for many years.
