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 70 square metres. Dwelling U1 (1BR) has 5 rooms totalling 62 square metres. Dwelling U2 (2BR) has 6 rooms totalling 64 square metres. Dwelling U3 (2BR) has 6 rooms totalling 68 square metres. Building footprint 144 square metres; open space 260 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.54, daylight 0.42, privacy 0.82, circulation 0.66, carbon 0.77, cost 0.27.
