Plan drawing of a fourplex on a 13.2 by 26.9 metre lot, 2 storeys, 4 dwellings, 22 rooms. Dwelling U0 (studio) has 4 rooms totalling 40 square metres. Dwelling U1 (1BR) has 5 rooms totalling 87 square metres. Dwelling U2 (1BR) has 5 rooms totalling 49 square metres. Dwelling U3 (2BR) has 6 rooms totalling 79 square metres. Building footprint 141 square metres; open space 211 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.82, daylight 0.27, privacy 0.79, circulation 0.52, carbon 0.78, cost 0.27.
