Le Corbusier and Pierre Jeanneret’s detached house and the semi-detached houses are part of the Stuttgart Weissenhof-Siedlung. The detached house is at No. 2 Bruckmannweg, and the semi-detached houses are at Nos. 1-3 Rathenaustrasse.The detached house is an implementation of the Citrohan model. The house has a cubic form seemingly made to float above the ground by the visible pilotis, recessed basement and coloured walls. The dominant element is a large central hall on two levels, to which are attached the service and individual rooms on the ground and gallery floors. The central hall opens towards the exterior through a large bay window on the south side; this was originally intended to contain a small interior garden arranged lengthwise. The roof terrace level consists of the garden surrounded by an attic, as well as living rooms and toilets. Characteristic of the free plan are the absence of fixed partitions, the curved partitions of the bathroom and the built-in furniture. The building’s high visibility is accentuated by the colourful painted facades.
The semi-detached houses are designed according to the “transformable house” model. The presence of movable elements allows great flexibility in the use of interior space and thus a maximum economy of space in the plan. From the Rathenaustrasse, one reaches the front door via an outside staircase leading to a terrace, its location suggesting an architectural promenade. An internal spiral staircase gives access both to the upper floor, containing the living and service rooms, and to the roof terrace level, with the roof garden occupying the entire surface, apart from a small library.
