You cannot allow precious space to be empty. It must be used without fail, but it does not litter the house. Take, for example, the territory under the stairs - for many families it is empty or, at best, plays the role of a warehouse. Did you know that you can use this space more favorably, for example, if you equip a closet, an open library and even an additional mini-bathroom or an office there? These and many other ideas can be found in a selection of 40 photos below.
