Plan drawing of a duplex on a 13.8 by 20.7 metre lot, 2 storeys, 2 dwellings, 12 rooms. Dwelling U0 (1BR) has 5 rooms totalling 66 square metres. Dwelling U1 (1BR) has 5 rooms totalling 66 square metres. Building footprint 76 square metres; open space 212 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.93, daylight 0.83, privacy 0.96, circulation 0.56, carbon 0.71, cost 0.18.
