Plan drawing of a fourplex on a 16.4 by 23.7 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 63 square metres. Dwelling U1 (1BR) has 5 rooms totalling 73 square metres. Dwelling U2 (2BR) has 6 rooms totalling 71 square metres. Dwelling U3 (2BR) has 6 rooms totalling 65 square metres. Building footprint 148 square metres; open space 238 square metres. This design is infeasible; failing categories: bad proportion, daylight failure. Objective scores, higher is better: density 1.00, daylight 0.36, privacy 0.87, circulation 0.60, carbon 0.78, cost 0.30.
