Plan drawing of a rowhouse on a 30.4 by 30.6 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 226 square metres. Dwelling U1 (2BR) has 9 rooms totalling 198 square metres. Dwelling U2 (2BR) has 9 rooms totalling 238 square metres. Dwelling U3 (2BR) has 9 rooms totalling 204 square metres. Building footprint 433 square metres; open space 498 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.70, daylight 0.59, privacy 0.86, circulation 0.62, carbon 0.93, cost 0.84.
