Plan drawing of a triplex on a 14.9 by 24.4 metre lot, 2 storeys, 3 dwellings, 20 rooms. Dwelling U0 (2BR) has 6 rooms totalling 58 square metres. Dwelling U1 (2BR) has 6 rooms totalling 42 square metres. Dwelling U2 (2BR) has 6 rooms totalling 100 square metres. Building footprint 111 square metres; open space 258 square metres. This design is infeasible; failing categories: bad proportion, daylight failure, insufficient area, no street access. Objective scores, higher is better: density 0.82, daylight 0.30, privacy 0.82, circulation 0.64, carbon 0.75, cost 0.36.
