If dont have enough space at home for everyone to live comfortably, is there anything you can do? Should you move? Or kick someone out? Not at all! The solution does not have to involve sacrifice. The solution is to change the walls: Instead of having fixed walls, make them movable.

This suggestion comes from the architects at the Madrid-based studio PKMN Architectures . They are behind the project Pequeas Grandes Casas or Little Big Houses, which enables fixed spaces to grow by utilizing movable walls and furniture. As the PKMN architects like to say, "every square foot is gold ."
