Plan drawing of a duplex on a 13.5 by 23.4 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (1BR) has 5 rooms totalling 89 square metres. Dwelling U1 (2BR) has 6 rooms totalling 89 square metres. Building footprint 109 square metres; open space 207 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.97, daylight 0.48, privacy 0.86, circulation 0.51, carbon 0.79, cost 0.48.
