Plan drawing of a fourplex on a 14.6 by 27.0 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 47 square metres. Dwelling U2 (2BR) has 6 rooms totalling 64 square metres. Dwelling U3 (2BR) has 6 rooms totalling 64 square metres. Building footprint 139 square metres; open space 256 square metres. This design is infeasible; failing categories: bad proportion, no street access. Objective scores, higher is better: density 0.63, daylight 0.44, privacy 0.76, circulation 0.70, carbon 0.77, cost 0.44.
