Heuristic-seeded NSGA-IIA+D · meets all 17 benchmark constraints. Brief B0006
Plan drawing of a adu pair on a 12.8 by 22.2 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (3BR) has 8 rooms totalling 86 square metres. Dwelling U1 (studio) has 4 rooms totalling 86 square metres. Building footprint 104 square metres; open space 176 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.94, daylight 0.43, privacy 0.82, circulation 0.65, carbon 0.78, cost 0.61.
