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 75 square metres. Dwelling U1 (1BR) has 5 rooms totalling 102 square metres. Dwelling U2 (1BR) has 5 rooms totalling 101 square metres. Dwelling U3 (2BR) has 6 rooms totalling 76 square metres. Building footprint 192 square metres; open space 225 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.92, daylight 0.43, privacy 0.76, circulation 0.71, carbon 0.84, cost 0.66.
