Plan drawing of a duplex on a 13.9 by 23.0 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (2BR) has 6 rooms totalling 62 square metres. Dwelling U1 (2BR) has 6 rooms totalling 62 square metres. Building footprint 73 square metres; open space 246 square metres. This design is infeasible; failing categories: bad proportion, insufficient area. Objective scores, higher is better: density 0.68, daylight 0.75, privacy 0.91, circulation 0.55, carbon 0.69, cost 0.01.
