The main space is divided in 3 zones : kitchen/dining , sitting area, sleeping area.
There is a line that separates the living area by the sleeping area that is done by a dividing panel (between the couch and bed) and furniture that are done in the same color as well as the walls of the bathroom thus reliefing space.
The main living space results in a clear compact form and the sleeping area is somehow masked behind this virtual line that separates the functions.
