This is the main room in a house of 550 m2, it was too small, uncomfortable and very outdated in aesthetic terms. Since the walls could not move, the problem was to increase the size of the room without incorporating space. Make it look bigger without actually being so. To do it, wc spaces were unified with the room and hallway. Windows were sequenced, geometric lines and colors were simplified as much as possible. The central wall is structural (necessary), so it is used as toilet screen, curved wing-shaped and treated in differents tones every face to hide their actual size.
