Plan drawing of a rowhouse on a 22.6 by 27.6 metre lot, 2 storeys, 3 dwellings, 29 rooms. Dwelling U0 (2BR) has 9 rooms totalling 107 square metres. Dwelling U1 (3BR) has 11 rooms totalling 166 square metres. Dwelling U2 (2BR) has 9 rooms totalling 304 square metres. Building footprint 288 square metres; open space 334 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.96, daylight 0.66, privacy 0.88, circulation 0.49, carbon 0.90, cost 0.81.
