Plan drawing of a triplex on a 16.0 by 22.4 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 53 square metres. Dwelling U2 (2BR) has 6 rooms totalling 95 square metres. Building footprint 110 square metres; open space 254 square metres. This design is infeasible; failing categories: adjacency violation, insufficient area, no street access. Objective scores, higher is better: density 0.71, daylight 0.78, privacy 0.78, circulation 0.62, carbon 0.76, cost 0.30.
