Fitting out a basement does not follow the same rules as a standard room. First and foremost, it is necessary to assess the feasibility of the project with the expertise of an architect or building specialist.

Once the floor leveling is done and the concrete slab is poured, it is necessary to install the technical ducts essential for the comfort of the future space. This includes the electrical network, needed to power the outlets and lights. Due to the constraints specific to a basement, it is often wise to multiply the light points for optimal comfort. However, this choice can influence the final cost of the work.
For a high-performance electrical system, expect about €200 per square meter. The total price will depend on the layout of the location, the type of equipment desired, and the specifics of the building. Contact Avenir Rénovations for a customized quote: our experts will advise you on the best solutions according to your needs and budget.

To make your basement livable, prioritize coverings suitable for the walls, floor, and ceiling. We particularly recommend the use of plasterboard (“placo”) for the walls and ceiling: it is an economical, reliable solution well-suited for thermal insulation. Once the installation is complete and the joints are dry, you can apply paint or install wallpaper. The budget will then depend on the type of finish chosen. For the floor, you can choose between tiles or parquet, and our craftsmen will handle the installation.
