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 201 square metres. Dwelling U1 (2BR) has 9 rooms totalling 245 square metres. Dwelling U2 (2BR) has 9 rooms totalling 213 square metres. Dwelling U3 (2BR) has 9 rooms totalling 217 square metres. Building footprint 438 square metres; open space 406 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.95, daylight 0.78, privacy 0.84, circulation 0.46, carbon 0.93, cost 0.85.
