Clapham House was the precursor for Superslender I. It has the structural logic and organization of Yemeni houses, the configuration logic of the Type A apartments, and the functional organization of a particular type of Victorian London shared apartment that had two living rooms at each end of upstairs and downstairs corridors. Parallel to these corridors was the staircase and along those corridors on each level were a shared bathroom and kitchen. These had less depth than the living rooms, meaning that they could have windows opening onto a lightwell, and the living rooms at the ends could also have a secondary window allowing cross ventilation.
This proposal has individual bathrooms. The kitchen remains a shared space and is also a shared circulation space but for the residents and not their visitors.
