CP-SATE · meets all 17 benchmark constraints. Brief B0066
Plan drawing of a adu pair on a 12.2 by 21.7 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (2BR) has 6 rooms totalling 75 square metres. Dwelling U1 (1BR) has 5 rooms totalling 75 square metres. Building footprint 81 square metres; open space 177 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.98, daylight 0.82, privacy 0.78, circulation 0.75, carbon 0.72, cost 0.44.
