Plan drawing of a rowhouse on a 25.5 by 27.5 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 94 square metres. Dwelling U1 (2BR) has 9 rooms totalling 121 square metres. Dwelling U2 (2BR) has 9 rooms totalling 112 square metres. Dwelling U3 (2BR) has 9 rooms totalling 157 square metres. Building footprint 242 square metres; open space 458 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.58, daylight 0.79, privacy 0.87, circulation 0.47, carbon 0.84, cost 0.39.
