Plan drawing of a fourplex on a 15.0 by 24.2 metre lot, 2 storeys, 4 dwellings, 22 rooms. Dwelling U0 (studio) has 4 rooms totalling 90 square metres. Dwelling U1 (1BR) has 5 rooms totalling 63 square metres. Dwelling U2 (1BR) has 5 rooms totalling 63 square metres. Dwelling U3 (2BR) has 6 rooms totalling 90 square metres. Building footprint 180 square metres; open space 180 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.94, daylight 0.49, privacy 0.74, circulation 0.64, carbon 0.83, cost 0.68.
