Gain new living space through loft conversion

Many houses have an unused space under the roof. To use the attic only as a storage space is too much, so much of the living space is simply given away. With a little skill and good ideas can be created from the dusty attic, a modern living space. However, the development should be planned with care and caution - the costs for the loft conversion should not be underestimated, per square meter of building area should cost 500 to 1,000 euros in costs, depending on the quality of the material and the working time invested.

From the Loft becomes living area - some tips for removal

When removing, some building codes must be followed. The legal regulations can be viewed in the respective state building regulations. As a builder, one must keep in mind that the height in the living spaces is at least 2.40 meters. The roof slope should be at a 40 to 50 degree angle to the ground. If the incline is lower, you may only use the space under the ridge. In the state building regulations, you will also find precise information on the fire protection regulations - in roof structures made of wood particularly important. Every change of use at the house is usually subject to approval. Therefore, the builders should get information from the local building authority, even before the actual construction planning. After 1990, the building use ordinance is somewhat relaxed: hereby the attic no longer counts as a floor space number. It indicates how much space the living space may have in relation to the size of the plot.

In the attic conversion you can perform the thermal insulation in parallel. This investment pays off both in summer and in winter: In summer, good insulation promises pleasantly cool temperatures in the living areas, while in winter it stays chilly and warm. For the thermal insulation special regulations of the energy saving regulation are prescribed for the heat protection. For a subsequent insulation of the attic, the so-called intermediate spar insulation can be carried out. You put about 20 centimeters of insulation between the rafters. If you perform the Thermal Insulation Measures in older homes, you may need to double the rafters to reach the desired dam height. For new buildings, the rafters usually already have enough depth. If the vapor-permeable vapor barrier has already been fitted, you can start with the cladding of the wall. For this, the Rigips plates or the Untersparrenverbundplatten be used. For the floor first boards or OSB boards are laid. In order not to be able to hear every step in the living areas below, a special impact sound insulation should be used. Only then will the usual floor covering be laid.

Finding the right staircase

As long as you comply with the legal building specifications, you can easily install a staircase yourself. If you are adept enough in your own home, you can especially make straight stairs on your own. For staircase construction, you need a construction supervision approval, as with laying tiles or wallpapering. The requirements relate primarily to their own safety. The width of the staircase should be at least 100 centimeters according to the building regulations, in closed apartments a width of 80 centimeters is sufficient. A duty is the handrail, which must be attached to both sides from a width of 125 centimeters. The stair railing must measure at least 90 centimeters high, in rooms with more than twelve meters fall height even 110 centimeters. When children live or visit the home, the step distance must not be more than twelve centimeters - for stairs without risers. The passage height at the stairs must measure at least two meters to avoid head injuries.

At the beginning of the stairway no door may be installed, which rises in the direction of the stairs. The hardest part of building a staircase is the slope and the number of steps. Determining the values ​​requires a bit of precision work. The inclination of the stairs should be between 25 and 40 degrees, it must not be more than 45 degrees. If the maximum step height is given as 19 centimeters, it is easy to calculate the number of steps. The so-called increment is on average 63 centimeters. For the calculation you use the following rule of thumb: 2x pitch height (2 × 19) + pitch (25) = 63-65 centimeters. If the attic remains without additional insulation, a space saving staircase should be installed. Such staircase closes airtight, so no energy is wasted. Thanks to the hatch railing, it is ensured that no one overlooks the staircase opening.

Loft conversion: rooflight window or dormer window

When loft conversions can actually determine whether the work expensive or cheaper. The dormer is not cheap, the cost depends on the amount of work, the material and the working hours. However, you have to expect a few thousand euros. For this purpose, a specialist should be ordered, a dormer is usually not built yourself. Somewhat cheaper is the installation of a roof residential window . Depending on the material and design, you can expect a price of 300 euros upwards. In addition there are the installation costs.

The windows bring light and fresh air into the attic. A good, space-saving alternative to the usual roof windows are the swing windows . The window area does not protrude so much during ventilation, so the space can be used for furniture. When loft conversions, the builder can do many jobs themselves. Whether insulation, drywall or floors - experienced home improvement can certainly do that on their own. However, you should also note that certain work on electrical lines or sanitary facilities should be carried out by a specialist.
