The design includes three voids that serve as intermediary spaces between inside and outside, gently connecting the house to the surrounding neighborhood while still ensuring privacy. Because buildings on triangular lots tend to include dead space in the acutely angled corners, the three corners in this house are used as exterior voids. This creates obtuse angles in the interior side, which gives the rooms a softer shape. The structure occupies the entire lot, conforming to the triangular site’s shape to avoid setback regulations.
