Essentially an infill duplex in a packed mixed use neighbourhood of San Francisco, this heavily glazed 4 storey town-house, referred to as ‘black mass’, and its contemporary design language stand out boldly amidst the mostly Victorian/ Edwardian and other classical vernacular of the houses around it. The façade, which stands directly on the road, is an interesting exercise in massing of volumes in the narrow space available. Imposing in its black painted finish of zinc panels that frame massive glazed surfaces, the design cleverly re-interprets the local building code which covers bay-window, cornice and awnings, and combines them into this contemporary articulation.
