Plan drawing of a rowhouse on a 19.9 by 22.1 metre lot, 2 storeys, 3 dwellings, 29 rooms. Dwelling U0 (2BR) has 9 rooms totalling 81 square metres. Dwelling U1 (3BR) has 11 rooms totalling 161 square metres. Dwelling U2 (2BR) has 9 rooms totalling 96 square metres. Building footprint 169 square metres; open space 270 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.84, daylight 0.62, privacy 0.88, circulation 0.56, carbon 0.80, cost 0.29.
