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 208 square metres. Dwelling U1 (2BR) has 9 rooms totalling 239 square metres. Dwelling U2 (2BR) has 9 rooms totalling 236 square metres. Dwelling U3 (2BR) has 9 rooms totalling 201 square metres. Building footprint 442 square metres; open space 493 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.72, daylight 0.76, privacy 0.85, circulation 0.48, carbon 0.93, cost 0.86.
