Plan drawing of a rowhouse on a 29.5 by 30.6 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 186 square metres. Dwelling U1 (2BR) has 9 rooms totalling 154 square metres. Dwelling U2 (2BR) has 9 rooms totalling 180 square metres. Dwelling U3 (2BR) has 9 rooms totalling 187 square metres. Building footprint 353 square metres; open space 548 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.58, daylight 0.62, privacy 0.94, circulation 0.57, carbon 0.90, cost 0.75.
