Plan drawing of a fourplex on a 17.0 by 26.0 metre lot, 2 storeys, 4 dwellings, 26 rooms. Dwelling U0 (2BR) has 6 rooms totalling 64 square metres. Dwelling U1 (2BR) has 6 rooms totalling 98 square metres. Dwelling U2 (2BR) has 6 rooms totalling 79 square metres. Dwelling U3 (2BR) has 6 rooms totalling 82 square metres. Building footprint 180 square metres; open space 254 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.92, daylight 0.70, privacy 0.82, circulation 0.62, carbon 0.82, cost 0.66.
