B0036-heuristic-0~r31

HeuristicA · meets all 17 benchmark constraints. Brief B0036

Plan drawing of a adu pair on a 16.3 by 19.9 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (2BR) has 6 rooms totalling 120 square metres. Dwelling U1 (1BR) has 5 rooms totalling 120 square metres. Building footprint 134 square metres; open space 195 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.61, privacy 0.80, circulation 0.69, carbon 0.83, cost 0.74.
