Plan drawing of a fourplex on a 13.2 by 26.9 metre lot, 2 storeys, 4 dwellings, 22 rooms. Dwelling U0 (studio) has 4 rooms totalling 81 square metres. Dwelling U1 (1BR) has 5 rooms totalling 51 square metres. Dwelling U2 (1BR) has 5 rooms totalling 59 square metres. Dwelling U3 (2BR) has 6 rooms totalling 73 square metres. Building footprint 152 square metres; open space 201 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.93, daylight 0.69, privacy 0.75, circulation 0.63, carbon 0.79, cost 0.56.
