Simulated annealingC · violates 1 of 17 benchmark constraints (1 violations). Brief B0048

Plan drawing of a adu pair on a 14.2 by 18.4 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (3BR) has 8 rooms totalling 82 square metres. Dwelling U1 (studio) has 4 rooms totalling 82 square metres. Building footprint 92 square metres; open space 166 square metres. This design is infeasible; failing categories: insufficient area. Objective scores, higher is better: density 1.00, daylight 0.61, privacy 0.88, circulation 0.58, carbon 0.75, cost 0.35.
