CP-SATE · meets all 17 benchmark constraints. Brief B0012
Plan drawing of a adu pair on a 16.6 by 21.5 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (2BR) has 6 rooms totalling 120 square metres. Dwelling U1 (1BR) has 5 rooms totalling 116 square metres. Building footprint 124 square metres; open space 231 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.94, daylight 0.88, privacy 0.79, circulation 0.81, carbon 0.81, cost 0.70.
