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 47 square metres. Dwelling U2 (2BR) has 6 rooms totalling 86 square metres. Building footprint 102 square metres; open space 168 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, no street access. Objective scores, higher is better: density 0.78, daylight 0.46, privacy 0.83, circulation 0.62, carbon 0.74, cost 0.15.
