To live in a house properly you must have the ability to sleep, eat, read, preserve clothes and items, receive friends, cooking, relaxing, and much more ..... to do whatever would need a home with plenty of space or even a studio in which all the spaces are optimized to the maximum.The project develops the idea of different functions in one compact unit. Sofa, bookcase, wardrobe, table and drawers make up a single volume in wood. The sofa converts into a bed for guests, the table opens giving access to shelves for dishes, a hanger for storing your coat and drawers for objects that we want to keep more to the hand. The bed opens only at night, giving rise to a desk during the day. The floor is on two levels with the introduction of a platform that allows store inside large objects, such as folding chairs and pillows and clothing, in the area of the wardrobe. The interior is designed by pure volume, the container, the platform and the kitchen, which is closed when not in use.
