CP-SATE · meets all 17 benchmark constraints. Brief B0030
Plan drawing of a adu pair on a 12.9 by 18.0 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (2BR) has 6 rooms totalling 72 square metres. Dwelling U1 (1BR) has 5 rooms totalling 67 square metres. Building footprint 76 square metres; open space 158 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.87, daylight 0.60, privacy 0.73, circulation 0.78, carbon 0.67, cost 0.11.
