Plan drawing of a duplex on a 14.4 by 20.5 metre lot, 2 storeys, 2 dwellings, 12 rooms. Dwelling U0 (1BR) has 5 rooms totalling 100 square metres. Dwelling U1 (1BR) has 5 rooms totalling 100 square metres. Building footprint 112 square metres; open space 182 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.54, privacy 0.83, circulation 0.63, carbon 0.80, cost 0.66.
