Plan drawing of a fourplex on a 14.4 by 39.3 metre lot, 2 storeys, 4 dwellings, 26 rooms. Dwelling U0 (2BR) has 6 rooms totalling 128 square metres. Dwelling U1 (2BR) has 6 rooms totalling 139 square metres. Dwelling U2 (2BR) has 6 rooms totalling 129 square metres. Dwelling U3 (2BR) has 6 rooms totalling 138 square metres. Building footprint 291 square metres; open space 274 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 1.00, daylight 0.37, privacy 0.83, circulation 0.66, carbon 0.89, cost 0.81.
