Plan drawing of a adu pair on a 14.8 by 21.3 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (3BR) has 8 rooms totalling 79 square metres. Dwelling U1 (studio) has 4 rooms totalling 79 square metres. Building footprint 96 square metres; open space 223 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, insufficient area. Objective scores, higher is better: density 0.88, daylight 0.65, privacy 0.82, circulation 0.59, carbon 0.76, cost 0.47.
