Plan drawing of a fourplex on a 14.6 by 26.9 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 78 square metres. Dwelling U1 (1BR) has 5 rooms totalling 94 square metres. Dwelling U2 (2BR) has 6 rooms totalling 69 square metres. Dwelling U3 (2BR) has 6 rooms totalling 103 square metres. Building footprint 186 square metres; open space 202 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.95, daylight 0.42, privacy 0.87, circulation 0.63, carbon 0.82, cost 0.58.
