Indeed, whatever the function of a building, it is essential to think about an optimal layout of the rooms as well as accessibility. Most often, when the family grows, it is necessary to transform certain rooms into a bedroom or bathrooms.

Although the interior design does not involve major work, there are nevertheless mandatory legal procedures.

Transform Your Lost Attic Space

Generally speaking, to be considered a convertible attic space, the height of the sub-ceiling must measure at least 1.80 m, and the slope of the roof must measure 45°. If your house has attic space that can be converted, you should know that these extra meters are very valuable. Indeed, if one day you decide to create a guest room or a room for the children, you just have to use this space.

If this is the case, you do not need to change the roof pitch or touch the frame. Since the space that you used as a storage room for old objects will be transformed into a living area, this will involve some administrative procedures. If the floor area obtained after the work does not exceed 20 m², a declaration of work will suffice.

However, a building permit is required if the floor area is more than 20 m². The development of the attic space also involves a technical study. Indeed, you must make sure that the floor is solid enough. Moreover, choosing a light material like wood or vinyl for the floor is preferable. If you also plan to separate the space, you should choose a movable partition rather than a dividing wall. There are some very attractive and decorative models.
