Plan drawing of a rowhouse on a 22.2 by 26.7 metre lot, 2 storeys, 3 dwellings, 27 rooms. Dwelling U0 (2BR) has 9 rooms totalling 178 square metres. Dwelling U1 (2BR) has 9 rooms totalling 196 square metres. Dwelling U2 (2BR) has 9 rooms totalling 174 square metres. Building footprint 274 square metres; open space 308 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.97, daylight 0.63, privacy 0.85, circulation 0.47, carbon 0.90, cost 0.71.
