Setting up a cellar: regulations to know
Before proceeding to any development or extension of a dwelling, it is necessary to inquire with the town hall of the town. Indeed, some work requires obtaining an authorization before being able to start. In some cases, no authorization can be issued, especially in cases where public health risks exist or if a state of natural and technological risks in the area is declared (ERNT diagnosis). This can happen in areas where the risk of flood is high for example. And if it is a building condominium, it is essential to consult the rules of co-ownership and obtain the agreement of the co-owners at the general meeting of co-ownership.
Added to this are the constraints in height and area. According to the Construction and Housing Code, certain standards must be respected in order to live in a room. The total area should not be less than 14 m² and the ceiling height must be at least 1 meter 80.
Works necessary for the transformation of a cellar
Many works must be undertaken to transform a cellar into a living room. The goal is to clean up the premises so that the cellar, often a source of moisture, becomes livable.
- Isolation is essential
The best is to choose an outside system so as not to reduce the surface inside. But it is also possible to install an insulation based on drywall or special waterproofing insulating materials. In addition to insulation, consideration should be given to heating provided by a boiler or radiators.
- Then come aeration and dehumidification
It is necessary that the air can circulate as it is the case in the different parts of a house. In practice, windows or ventilation grids can be placed at the level of the unburied portions of the walls. This step is very important because it avoids moisture and the appearance of mold. Windows (or other openings) also help bring natural light into the new living room.
- We must also think about electricity
It is advisable to use a certified professional electrician to draw up an electrical assessment. Work and modifications will be carried out taking into account the safety standards in force.
- Then there is the water supply
In addition to the arrival of water, it is also necessary to set up a sewage pumping system.
- Finally, we must not neglect the hunt for pests
Depending on the location, it may be necessary to use a derterminator or an insect exterminator to get rid of small bugs unwanted.
