Simulated annealingC · meets all 17 benchmark constraints. Brief B0054
Plan drawing of a adu pair on a 12.8 by 23.5 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (2BR) has 6 rooms totalling 71 square metres. Dwelling U1 (1BR) has 5 rooms totalling 71 square metres. Building footprint 101 square metres; open space 204 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.65, daylight 0.76, privacy 0.80, circulation 0.54, carbon 0.78, cost 0.52.
