Plan drawing of a triplex on a 14.1 by 21.5 metre lot, 2 storeys, 3 dwellings, 17 rooms. Dwelling U0 (studio) has 4 rooms totalling 34 square metres. Dwelling U1 (1BR) has 5 rooms totalling 47 square metres. Dwelling U2 (2BR) has 6 rooms totalling 82 square metres. Building footprint 97 square metres; open space 201 square metres. This design is infeasible; failing categories: bad proportion, daylight failure. Objective scores, higher is better: density 0.63, daylight 0.50, privacy 0.73, circulation 0.57, carbon 0.73, cost 0.27.
