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 167 square metres. Dwelling U1 (2BR) has 9 rooms totalling 148 square metres. Dwelling U2 (2BR) has 9 rooms totalling 137 square metres. Dwelling U3 (2BR) has 9 rooms totalling 152 square metres. Building footprint 302 square metres; open space 462 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.73, daylight 0.72, privacy 0.89, circulation 0.58, carbon 0.88, cost 0.67.
