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 87 square metres. Dwelling U1 (1BR) has 5 rooms totalling 99 square metres. Dwelling U2 (1BR) has 5 rooms totalling 114 square metres. Dwelling U3 (2BR) has 6 rooms totalling 72 square metres. Building footprint 203 square metres; open space 214 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 1.00, daylight 0.41, privacy 0.80, circulation 0.64, carbon 0.84, cost 0.72.
