CP-SATE · meets all 17 benchmark constraints. Brief B0060
Plan drawing of a adu pair on a 12.6 by 19.3 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (3BR) has 8 rooms totalling 96 square metres. Dwelling U1 (studio) has 4 rooms totalling 96 square metres. Building footprint 100 square metres; open space 144 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.53, privacy 0.85, circulation 0.79, carbon 0.80, cost 0.53.
