Restructuring the house for erecting the attic floor
In order to rebuild the attic under the attic, you first need to find out whether the foundation can withstand the additional burden on the house. If the building is only being built, then in the calculations it is already taken into account. And if it is decided to build an attic above the restored house, then it is necessary to strengthen it. For greater reliability, additional supports are installed so that the building can withstand a large load.
When rebuilding, it is necessary to take into account the type of the roof of the house. If the roof has a large angle of the slope, then the room on the attic floor turns out to be small. It should be noted that the angle of inclination of the roof occupies a large area of the floor.
Buying a house, taking into account the fact that there will be a built up attic, you need to pay attention to the roof. The attic floor is not necessarily built from scratch, it can be altered from the attic.
Calculating the dimensions of the roof roof
The height of the ceilings is the main condition for the construction of the attic floor. If the walls are not high enough, there may be problems with the equipment of the superstructure under the living room, since it will contain various furniture, including cabinets.
Please note that for free movement of people in such a room and for their safety, the minimum height of the roof is 2.5 m. If the ceilings are lower, then the room is more suitable for an attic than for an attic there.
In order to ensure the required height in the superstructure, the line of the broken roof must be at a height of at least 3 m.
When purchasing the necessary material for covering the roof, it is necessary to draw an exact plan where the roof dimensions, houses and height will be calculated and painted.
To determine the height of the roof of the built-up floor, you need to consider some factors. If in the drawing of the attic everything will be reasonably calculated, then the superstructure will be as comfortable as possible.
Drawing of the roof of the attic floor
Before you begin the rebuilding of the attic under the attic or the superstructure of the additional floor, a drawing should be made. It should specify the exact calculations, which in the future will help without special difficulties to build an additional floor.
In order for the data in the drawing to be as accurate as possible, it is necessary to begin with the calculation of the construction of rafters. With the choice of their length, there should be no particular problems, since their dimensions are clearly indicated in the building codes.
Double-pitched broken roof is most suitable for building an attic.
Please note that broken roofing, unlike a saddle roof, increases the load on the walls of the house, so there should be installed as many bearing supports as possible for sufficient reliability.
To build an attic above the old building, you need to install additional supports along the perimeter of the whole house. This will help ease the load on the walls.
The ventilation system should be described in the calculations. To the room was not very stuffy, you need to determine how the air will circulate in the room.
An important part of the drawing is the lighting of the superstructure. For the attic floor, one window will suffice.
It should be noted that dormer windows give about 40% more lighting than conventional, so it is recommended to install this option of natural light.
The height of the add-in window does not have any size constraints. But the bottom edge should be at least 90cm. This should also be included in the drawing.
The more accurate the calculations will be in the attic drawing and the more they are there, the longer and safer the superstructure will be.
