In the longitudinal section of the studio house, three floors are clearly visible. Below that, three points of foundation are clearly shown. On the first floor there is a void on the left, which is not clearly indicated as an outdoor space on this drawing. Furthermore, two spaces with doors are depicted. On the second floor, above these rooms, two equal rooms are drawn, only the leftmost room has a door. Also on the second floor is the studio space, whose ceiling extends to the second floor. In the studio there is a spiral staircase that leads to the roof terrace. Previous designs (DOES033+ and DOES034+) indicate one pillar. In this design it has been changed to two and this has been implemented. On the upper left is Feuille No. 5. On the lower left is Coupe A-B. The floor plan in DOES038+ shows exactly where the building is cut. Written in pencil below the void are the words Terrain Naturel. For all spaces, the height is indicated. Below the drawing are the project name, client, location, scale, date.
