Heuristic-seeded NSGA-IIA+D · meets all 17 benchmark constraints. Brief B0049
Plan drawing of a courtyard on a 19.2 by 24.2 metre lot, 2 storeys, 4 dwellings, 25 rooms. Dwelling U0 (1BR) has 5 rooms totalling 65 square metres. Dwelling U1 (2BR) has 6 rooms totalling 67 square metres. Dwelling U2 (2BR) has 6 rooms totalling 65 square metres. Dwelling U3 (2BR) has 6 rooms totalling 67 square metres. Building footprint 154 square metres; open space 302 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.74, daylight 0.48, privacy 0.80, circulation 0.62, carbon 0.70, cost 0.33.
