Plan drawing of a duplex on a 15.1 by 21.0 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (2BR) has 6 rooms totalling 101 square metres. Dwelling U1 (2BR) has 6 rooms totalling 101 square metres. Building footprint 113 square metres; open space 201 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.98, daylight 0.75, privacy 0.86, circulation 0.58, carbon 0.79, cost 0.65.
