Flat was born from our client's choice to have an open but also closed loft; for this reason we thought of a dynamic space that can be modulated and changes appearance through sliding and movable walls. Thus both the bookcases and the doors slide on tracks, transforming the spaces to the needs of the moment. A "flat" floor, open with large transparent windows or semi-closed elements such as bookcases, animates the space through the movement of the people who live there.
