Plan drawing of a triplex on a 13.2 by 21.0 metre lot, 2 storeys, 3 dwellings, 17 rooms. Dwelling U0 (studio) has 4 rooms totalling 39 square metres. Dwelling U1 (1BR) has 5 rooms totalling 56 square metres. Dwelling U2 (2BR) has 6 rooms totalling 95 square metres. Building footprint 110 square metres; open space 164 square metres. This design is infeasible; failing categories: bad proportion. Objective scores, higher is better: density 0.88, daylight 0.55, privacy 0.74, circulation 0.63, carbon 0.75, cost 0.44.
