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 71 square metres. Dwelling U1 (2BR) has 6 rooms totalling 96 square metres. Dwelling U2 (2BR) has 6 rooms totalling 72 square metres. Dwelling U3 (2BR) has 6 rooms totalling 95 square metres. Building footprint 190 square metres; open space 246 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.68, privacy 0.82, circulation 0.61, carbon 0.83, cost 0.69.
