B0060-sketch-0-963

Random sketch + repairF′ · meets all 17 benchmark constraints. Brief B0060

Plan drawing of a adu pair on a 12.6 by 19.3 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (3BR) has 8 rooms totalling 87 square metres. Dwelling U1 (studio) has 4 rooms totalling 87 square metres. Building footprint 99 square metres; open space 144 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.98, daylight 0.54, privacy 0.92, circulation 0.59, carbon 0.76, cost 0.40.
