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 43 square metres. Dwelling U1 (1BR) has 5 rooms totalling 41 square metres. Dwelling U2 (2BR) has 6 rooms totalling 84 square metres. Building footprint 96 square metres; open space 170 square metres. This design is infeasible; failing categories: bad proportion, insufficient area. Objective scores, higher is better: density 1.00, daylight 0.67, privacy 0.74, circulation 0.64, carbon 0.72, cost 0.33.
