Random sketch + repairF′ · violates 1 of 17 benchmark constraints (1 violations). Brief B0024

Plan drawing of a adu pair on a 11.7 by 21.2 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (3BR) has 8 rooms totalling 74 square metres. Dwelling U1 (studio) has 4 rooms totalling 74 square metres. Building footprint 84 square metres; open space 156 square metres. This design is infeasible; failing categories: insufficient area. Objective scores, higher is better: density 0.93, daylight 0.65, privacy 0.82, circulation 0.67, carbon 0.73, cost 0.27.
