Plan drawing of a rowhouse on a 27.0 by 31.4 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 175 square metres. Dwelling U1 (2BR) has 9 rooms totalling 146 square metres. Dwelling U2 (2BR) has 9 rooms totalling 189 square metres. Dwelling U3 (2BR) has 9 rooms totalling 156 square metres. Building footprint 333 square metres; open space 510 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.59, daylight 0.67, privacy 0.87, circulation 0.62, carbon 0.89, cost 0.67.
