Plan drawing of a duplex on a 18.0 by 21.2 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (2BR) has 6 rooms totalling 114 square metres. Dwelling U1 (2BR) has 6 rooms totalling 114 square metres. Building footprint 134 square metres; open space 243 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.58, privacy 0.83, circulation 0.58, carbon 0.83, cost 0.68.
