In order to enlarge their apartment located in a historical building, the owners have bought a room on the lower floor and two adjoining courtyards. The project will use the new room on the ground floor to create a studio with independent entrance. The new series of spaces (bigger yard-studio-smaller yard) is conceived as a single, uninterrupted sequence thanks to the use of the same flooring material (wood). An open staircase leads to the top of the house. The construction of a new bathroom will alter the current arrangement of the bedroom area.
