Plan drawing of a duplex on a 17.5 by 22.1 metre lot, 2 storeys, 2 dwellings, 12 rooms. Dwelling U0 (1BR) has 5 rooms totalling 104 square metres. Dwelling U1 (1BR) has 5 rooms totalling 104 square metres. Building footprint 122 square metres; open space 266 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.67, privacy 0.74, circulation 0.65, carbon 0.82, cost 0.71.
