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 116 square metres. Dwelling U1 (1BR) has 5 rooms totalling 116 square metres. Building footprint 148 square metres; open space 242 square metres. This design is infeasible; failing categories: adjacency violation. Objective scores, higher is better: density 1.00, daylight 0.60, privacy 0.90, circulation 0.51, carbon 0.84, cost 0.78.
