Plan drawing of a rowhouse on a 29.5 by 30.6 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 224 square metres. Dwelling U1 (2BR) has 9 rooms totalling 231 square metres. Dwelling U2 (2BR) has 9 rooms totalling 244 square metres. Dwelling U3 (2BR) has 9 rooms totalling 226 square metres. Building footprint 462 square metres; open space 428 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.93, daylight 0.82, privacy 0.85, circulation 0.48, carbon 0.94, cost 0.86.
