Plan drawing of a rowhouse on a 25.0 by 30.3 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 105 square metres. Dwelling U1 (2BR) has 9 rooms totalling 114 square metres. Dwelling U2 (2BR) has 9 rooms totalling 166 square metres. Dwelling U3 (2BR) has 9 rooms totalling 135 square metres. Building footprint 260 square metres; open space 490 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.55, daylight 0.73, privacy 0.89, circulation 0.61, carbon 0.85, cost 0.48.
