Plan drawing of a fourplex on a 14.6 by 26.9 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 70 square metres. Dwelling U1 (1BR) has 5 rooms totalling 68 square metres. Dwelling U2 (2BR) has 6 rooms totalling 74 square metres. Dwelling U3 (2BR) has 6 rooms totalling 64 square metres. Building footprint 157 square metres; open space 238 square metres. This design is infeasible; failing categories: bad proportion. Objective scores, higher is better: density 0.72, daylight 0.35, privacy 0.79, circulation 0.59, carbon 0.80, cost 0.37.
