Plan drawing of a fourplex on a 13.7 by 31.0 metre lot, 2 storeys, 4 dwellings, 22 rooms. Dwelling U0 (studio) has 4 rooms totalling 96 square metres. Dwelling U1 (1BR) has 5 rooms totalling 54 square metres. Dwelling U2 (1BR) has 5 rooms totalling 76 square metres. Dwelling U3 (2BR) has 6 rooms totalling 74 square metres. Building footprint 163 square metres; open space 256 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.70, daylight 0.45, privacy 0.80, circulation 0.70, carbon 0.81, cost 0.51.
