Plan drawing of a fourplex on a 15.0 by 23.9 metre lot, 2 storeys, 4 dwellings, 22 rooms. Dwelling U0 (studio) has 4 rooms totalling 57 square metres. Dwelling U1 (1BR) has 5 rooms totalling 49 square metres. Dwelling U2 (1BR) has 5 rooms totalling 45 square metres. Dwelling U3 (2BR) has 6 rooms totalling 62 square metres. Building footprint 120 square metres; open space 239 square metres. This design is infeasible; failing categories: insufficient area. Objective scores, higher is better: density 1.00, daylight 0.45, privacy 0.76, circulation 0.63, carbon 0.75, cost 0.41.
