Plan drawing of a rowhouse on a 25.5 by 27.5 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 113 square metres. Dwelling U2 (2BR) has 9 rooms totalling 146 square metres. Dwelling U3 (2BR) has 9 rooms totalling 139 square metres. Building footprint 287 square metres; open space 416 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.79, daylight 0.65, privacy 0.87, circulation 0.59, carbon 0.87, cost 0.61.
