Plan drawing of a duplex on a 15.3 by 19.8 metre lot, 2 storeys, 2 dwellings, 12 rooms. Dwelling U0 (1BR) has 5 rooms totalling 86 square metres. Dwelling U1 (1BR) has 5 rooms totalling 86 square metres. Building footprint 97 square metres; open space 216 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.75, daylight 0.75, privacy 0.95, circulation 0.55, carbon 0.77, cost 0.40.
