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 45 square metres. Dwelling U1 (1BR) has 5 rooms totalling 75 square metres. Dwelling U2 (1BR) has 5 rooms totalling 50 square metres. Dwelling U3 (2BR) has 6 rooms totalling 70 square metres. Building footprint 130 square metres; open space 223 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.71, daylight 0.48, privacy 0.75, circulation 0.70, carbon 0.77, cost 0.33.
