HeuristicA · violates 1 of 17 benchmark constraints (1 violations). Brief B0006

Plan drawing of a adu pair on a 12.8 by 22.2 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (3BR) has 8 rooms totalling 88 square metres. Dwelling U1 (studio) has 4 rooms totalling 88 square metres. Building footprint 102 square metres; open space 182 square metres. This design is infeasible; failing categories: adjacency violation. Objective scores, higher is better: density 0.92, daylight 0.59, privacy 0.79, circulation 0.59, carbon 0.77, cost 0.59.
