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 54 square metres. Dwelling U1 (2BR) has 6 rooms totalling 57 square metres. Dwelling U2 (2BR) has 6 rooms totalling 111 square metres. Building footprint 124 square metres; open space 242 square metres. This design is infeasible; failing categories: bad proportion, insufficient area, no street access. Objective scores, higher is better: density 0.98, daylight 0.35, privacy 0.82, circulation 0.66, carbon 0.77, cost 0.38.
