NSGA-IID · meets all 17 benchmark constraints. Brief B0000
Plan drawing of a adu pair on a 16.5 by 19.9 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 85 square metres; open space 244 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.57, daylight 0.82, privacy 0.81, circulation 0.54, carbon 0.74, cost 0.29.
