Plan drawing of a fourplex on a 14.6 by 27.0 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 51 square metres. Dwelling U1 (1BR) has 5 rooms totalling 90 square metres. Dwelling U2 (2BR) has 6 rooms totalling 69 square metres. Dwelling U3 (2BR) has 6 rooms totalling 73 square metres. Building footprint 153 square metres; open space 240 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.75, daylight 0.34, privacy 0.82, circulation 0.67, carbon 0.79, cost 0.35.
