Plan drawing of a rowhouse on a 24.4 by 28.2 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 137 square metres. Dwelling U1 (2BR) has 9 rooms totalling 103 square metres. Dwelling U2 (2BR) has 9 rooms totalling 117 square metres. Dwelling U3 (2BR) has 9 rooms totalling 124 square metres. Building footprint 241 square metres; open space 443 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.65, daylight 0.72, privacy 0.87, circulation 0.58, carbon 0.84, cost 0.34.
