Plan drawing of a fourplex on a 12.7 by 31.9 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 79 square metres. Dwelling U1 (1BR) has 5 rooms totalling 69 square metres. Dwelling U2 (2BR) has 6 rooms totalling 69 square metres. Dwelling U3 (2BR) has 6 rooms totalling 79 square metres. Building footprint 185 square metres; open space 220 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, daylight failure, no street access. Objective scores, higher is better: density 0.85, daylight 0.29, privacy 0.80, circulation 0.51, carbon 0.81, cost 0.43.
