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 193 square metres. Dwelling U1 (3BR) has 11 rooms totalling 94 square metres. Dwelling U2 (2BR) has 9 rooms totalling 80 square metres. Building footprint 183 square metres; open space 260 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.96, daylight 0.59, privacy 0.94, circulation 0.49, carbon 0.82, cost 0.41.
