Plan drawing of a rowhouse on a 29.5 by 30.6 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 223 square metres. Dwelling U1 (2BR) has 9 rooms totalling 229 square metres. Dwelling U2 (2BR) has 9 rooms totalling 236 square metres. Dwelling U3 (2BR) has 9 rooms totalling 235 square metres. Building footprint 461 square metres; open space 437 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.92, daylight 0.59, privacy 0.89, circulation 0.48, carbon 0.94, cost 0.90.
