Plan drawing of a adu pair on a 12.9 by 18.0 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (2BR) has 6 rooms totalling 64 square metres. Dwelling U1 (1BR) has 5 rooms totalling 64 square metres. Building footprint 74 square metres; open space 158 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion. Objective scores, higher is better: density 0.88, daylight 0.58, privacy 0.86, circulation 0.57, carbon 0.71, cost 0.17.
