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 180 square metres. Dwelling U1 (2BR) has 9 rooms totalling 227 square metres. Dwelling U2 (2BR) has 9 rooms totalling 262 square metres. Dwelling U3 (2BR) has 9 rooms totalling 221 square metres. Building footprint 445 square metres; open space 484 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.73, daylight 0.53, privacy 0.93, circulation 0.47, carbon 0.93, cost 0.89.
