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 28 square metres. Dwelling U1 (1BR) has 5 rooms totalling 37 square metres. Dwelling U2 (2BR) has 6 rooms totalling 65 square metres. Building footprint 79 square metres; open space 189 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, daylight failure, insufficient area, no street access. Objective scores, higher is better: density 0.73, daylight 0.49, privacy 0.77, circulation 0.60, carbon 0.68, cost 0.00.
