Plan drawing of a fourplex on a 15.0 by 24.2 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 67 square metres. Dwelling U2 (1BR) has 5 rooms totalling 77 square metres. Dwelling U3 (2BR) has 6 rooms totalling 64 square metres. Building footprint 155 square metres; open space 200 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.74, daylight 0.36, privacy 0.85, circulation 0.61, carbon 0.80, cost 0.42.
