Random sketch + repairF′ · meets all 17 benchmark constraints. Brief B0018
Plan drawing of a adu pair on a 17.5 by 21.8 metre lot, 2 storeys, 2 dwellings, 15 rooms. Dwelling U0 (3BR) has 8 rooms totalling 123 square metres. Dwelling U1 (1BR) has 5 rooms totalling 123 square metres. Building footprint 148 square metres; open space 242 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.59, privacy 0.92, circulation 0.50, carbon 0.84, cost 0.72.
