Plan drawing of a fourplex on a 14.6 by 27.0 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 82 square metres. Dwelling U1 (1BR) has 5 rooms totalling 78 square metres. Dwelling U2 (2BR) has 6 rooms totalling 77 square metres. Dwelling U3 (2BR) has 6 rooms totalling 82 square metres. Building footprint 184 square metres; open space 204 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.45, privacy 0.76, circulation 0.64, carbon 0.82, cost 0.66.
