In a multifamily housing project, a geometric tiling system reorganizes traditional domestic space. Contrary to common large housing complexes, this tiled mass-courtyard system creates unique “blocks” within the project that promote neighborly interactions and create individualized spaces. A seven-square tiling system aggregates in both plan and section, where each set of seven squares forms a single block, and each square acts as a different housing program. Each block contains a  large two-level apartment, two one-bedroom apartments connected by a shared corridor, and a small studio apartment, all accessed by the same exterior staircase. The largest square is reserved for a courtyard that acts as a shared communal space and creates a thoroughfare through the site.
