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 63 square metres. Dwelling U1 (1BR) has 5 rooms totalling 63 square metres. Building footprint 78 square metres; open space 235 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.50, daylight 0.88, privacy 0.89, circulation 0.46, carbon 0.72, cost 0.33.
