CP-SATE · meets all 17 benchmark constraints. Brief B0050
Plan drawing of a duplex on a 14.0 by 17.5 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (2BR) has 6 rooms totalling 80 square metres. Dwelling U1 (2BR) has 6 rooms totalling 80 square metres. Building footprint 84 square metres; open space 161 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.93, daylight 0.54, privacy 0.82, circulation 0.73, carbon 0.74, cost 0.27.
