Plan drawing of a fourplex on a 12.0 by 29.2 metre lot, 2 storeys, 4 dwellings, 26 rooms. Dwelling U0 (2BR) has 6 rooms totalling 69 square metres. Dwelling U1 (2BR) has 6 rooms totalling 63 square metres. Dwelling U2 (2BR) has 6 rooms totalling 68 square metres. Dwelling U3 (2BR) has 6 rooms totalling 64 square metres. Building footprint 144 square metres; open space 199 square metres. This design is infeasible; failing categories: bad proportion, no street access. Objective scores, higher is better: density 0.86, daylight 0.36, privacy 0.88, circulation 0.66, carbon 0.77, cost 0.16.
