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 99 square metres. Dwelling U1 (1BR) has 5 rooms totalling 99 square metres. Building footprint 118 square metres; open space 270 square metres. This design is infeasible; failing categories: adjacency violation. Objective scores, higher is better: density 0.68, daylight 0.65, privacy 0.86, circulation 0.59, carbon 0.80, cost 0.45.
