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 36 square metres. Dwelling U1 (1BR) has 5 rooms totalling 52 square metres. Dwelling U2 (1BR) has 5 rooms totalling 40 square metres. Dwelling U3 (2BR) has 6 rooms totalling 48 square metres. Building footprint 99 square metres; open space 261 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, insufficient area, no street access. Objective scores, higher is better: density 0.73, daylight 0.64, privacy 0.77, circulation 0.65, carbon 0.70, cost 0.06.
