Heuristic-seeded NSGA-IIA+D · meets all 17 benchmark constraints. Brief B0005
Plan drawing of a triplex on a 15.8 by 20.8 metre lot, 2 storeys, 3 dwellings, 18 rooms. Dwelling U0 (1BR) has 5 rooms totalling 62 square metres. Dwelling U1 (1BR) has 5 rooms totalling 63 square metres. Dwelling U2 (2BR) has 6 rooms totalling 125 square metres. Building footprint 142 square metres; open space 192 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.93, daylight 0.48, privacy 0.77, circulation 0.63, carbon 0.81, cost 0.68.
