H. HERTZBERGER, 1968-1970, Gebbenlaan, Delft
Prototypes of a more extensive layout, these eight dwellings are deliberately left incomplete and are to be internally organized and adapted to changing circumstances by the occupants themselves. The basic elements provided are two fixed cores (stairwell and kitchen/wet services) with floors stepping up in half-levels. The entrance, roof terrace and balcony may also be drawn into the building. The facade deploys a standard framework to be filled in with glazing or panels. Partitions for gardens and roof terraces are present in a rudimentary form as concrete blocks and steel frames.
