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 103 square metres. Dwelling U1 (1BR) has 5 rooms totalling 103 square metres. Building footprint 114 square metres; open space 272 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.90, daylight 0.82, privacy 0.86, circulation 0.67, carbon 0.80, cost 0.60.
