CP-SATE · meets all 17 benchmark constraints. Brief B0042
Plan drawing of a adu pair on a 14.8 by 21.3 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (3BR) has 8 rooms totalling 94 square metres. Dwelling U1 (studio) has 4 rooms totalling 94 square metres. Building footprint 100 square metres; open space 223 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.94, daylight 0.73, privacy 0.80, circulation 0.76, carbon 0.79, cost 0.61.
