Created in collaboration with architect Christopher Deam, this 1950's Berkeley hillside residence is built directly upon a defunct concrete water cistern embedded into the sloped terrain. The extensive renovation creates an open plan to maximize light and views of San Francisco. The interior is conceived as being analogous to an interior of a trailer or boat, where a maximum of operations and functions are efficiently compressed within a fixed spatial volume. Elements of architecture and furniture are programmatically fused, providing the client with a density of hidden functions behind the changing pattern sliding cabinet doors. Originally unusable, the cistern space is made accessible from the main living space via a perforated metal ladder and stairs, which are suspended directly from the concrete cistern ceiling.
