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 51 square metres. Dwelling U1 (1BR) has 5 rooms totalling 52 square metres. Dwelling U2 (1BR) has 5 rooms totalling 47 square metres. Dwelling U3 (2BR) has 6 rooms totalling 56 square metres. Building footprint 116 square metres; open space 244 square metres. This design is infeasible; failing categories: bad proportion, daylight failure, insufficient area, no street access. Objective scores, higher is better: density 0.95, daylight 0.47, privacy 0.76, circulation 0.64, carbon 0.73, cost 0.37.
