Plan drawing of a triplex on a 11.6 by 23.5 metre lot, 2 storeys, 3 dwellings, 18 rooms. Dwelling U0 (1BR) has 5 rooms totalling 38 square metres. Dwelling U1 (1BR) has 5 rooms totalling 38 square metres. Dwelling U2 (2BR) has 6 rooms totalling 76 square metres. Building footprint 86 square metres; open space 186 square metres. This design is infeasible; failing categories: bad proportion, insufficient area, no street access. Objective scores, higher is better: density 0.84, daylight 0.38, privacy 0.82, circulation 0.59, carbon 0.70, cost 0.00.
