CP-SATE · meets all 17 benchmark constraints. Brief B0048
Plan drawing of a adu pair on a 14.2 by 18.4 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (3BR) has 8 rooms totalling 84 square metres. Dwelling U1 (studio) has 4 rooms totalling 81 square metres. Building footprint 88 square metres; open space 171 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.91, daylight 0.66, privacy 0.89, circulation 0.72, carbon 0.75, cost 0.41.
