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 74 square metres. Dwelling U1 (1BR) has 5 rooms totalling 80 square metres. Dwelling U2 (2BR) has 6 rooms totalling 73 square metres. Dwelling U3 (2BR) has 6 rooms totalling 81 square metres. Building footprint 174 square metres; open space 213 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.85, daylight 0.62, privacy 0.78, circulation 0.66, carbon 0.81, cost 0.63.
