Plan drawing of a triplex on a 15.8 by 20.8 metre lot, 2 storeys, 3 dwellings, 18 rooms. Dwelling U0 (1BR) has 5 rooms totalling 56 square metres. Dwelling U1 (1BR) has 5 rooms totalling 61 square metres. Dwelling U2 (2BR) has 6 rooms totalling 117 square metres. Building footprint 132 square metres; open space 204 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, no street access. Objective scores, higher is better: density 0.82, daylight 0.47, privacy 0.85, circulation 0.63, carbon 0.79, cost 0.50.
