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 87 square metres. Dwelling U1 (1BR) has 5 rooms totalling 81 square metres. Dwelling U2 (2BR) has 6 rooms totalling 80 square metres. Dwelling U3 (2BR) has 6 rooms totalling 88 square metres. Building footprint 183 square metres; open space 220 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.83, daylight 0.36, privacy 0.85, circulation 0.60, carbon 0.82, cost 0.53.
