Plan drawing of a rowhouse on a 25.0 by 30.3 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 122 square metres. Dwelling U1 (2BR) has 9 rooms totalling 142 square metres. Dwelling U2 (2BR) has 9 rooms totalling 127 square metres. Dwelling U3 (2BR) has 9 rooms totalling 172 square metres. Building footprint 282 square metres; open space 480 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.64, daylight 0.58, privacy 0.93, circulation 0.47, carbon 0.87, cost 0.63.
