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 81 square metres. Dwelling U1 (1BR) has 5 rooms totalling 78 square metres. Dwelling U2 (2BR) has 6 rooms totalling 80 square metres. Dwelling U3 (2BR) has 6 rooms totalling 79 square metres. Building footprint 173 square metres; open space 230 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.76, daylight 0.36, privacy 0.76, circulation 0.70, carbon 0.81, cost 0.63.
