D’ALIO 31 is the interior reform of a top-floor apartment of 40 m2 where the bathroom sets itself up as the main piece of the house, being filter between the public and private space and at the same time the straight connection with its practicable roof throw a courtyard that lets you have a shower in the open air. The flexible walls of the bathroom let us read the apartment as a unique space or as three rooms: living-dining-kitchen, bathroom and bedroom, being able to control the privacy in case of having guests.
