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 90 square metres. Dwelling U1 (1BR) has 5 rooms totalling 96 square metres. Dwelling U2 (1BR) has 5 rooms totalling 95 square metres. Dwelling U3 (2BR) has 6 rooms totalling 92 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 0.40, privacy 0.76, circulation 0.72, carbon 0.85, cost 0.69.
