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 171 square metres. Dwelling U1 (2BR) has 9 rooms totalling 189 square metres. Dwelling U2 (2BR) has 9 rooms totalling 196 square metres. Dwelling U3 (2BR) has 9 rooms totalling 168 square metres. Building footprint 362 square metres; open space 400 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.98, daylight 0.60, privacy 0.84, circulation 0.45, carbon 0.91, cost 0.76.
