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 67 square metres. Dwelling U1 (1BR) has 5 rooms totalling 67 square metres. Building footprint 77 square metres; open space 212 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.96, daylight 0.89, privacy 0.86, circulation 0.60, carbon 0.72, cost 0.43.
