Plan drawing of a fourplex on a 12.0 by 29.2 metre lot, 2 storeys, 4 dwellings, 26 rooms. Dwelling U0 (2BR) has 6 rooms totalling 64 square metres. Dwelling U1 (2BR) has 6 rooms totalling 63 square metres. Dwelling U2 (2BR) has 6 rooms totalling 63 square metres. Dwelling U3 (2BR) has 6 rooms totalling 64 square metres. Building footprint 148 square metres; open space 195 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, daylight failure, insufficient area, no street access. Objective scores, higher is better: density 0.90, daylight 0.45, privacy 0.79, circulation 0.51, carbon 0.75, cost 0.26.
