Plan drawing of a triplex on a 13.5 by 27.4 metre lot, 2 storeys, 3 dwellings, 17 rooms. Dwelling U0 (studio) has 4 rooms totalling 55 square metres. Dwelling U1 (1BR) has 5 rooms totalling 52 square metres. Dwelling U2 (2BR) has 6 rooms totalling 107 square metres. Building footprint 145 square metres; open space 227 square metres. This design is infeasible; failing categories: bad proportion, no street access. Objective scores, higher is better: density 0.85, daylight 0.32, privacy 0.78, circulation 0.52, carbon 0.81, cost 0.51.
