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 56 square metres. Dwelling U1 (2BR) has 6 rooms totalling 60 square metres. Dwelling U2 (2BR) has 6 rooms totalling 58 square metres. Dwelling U3 (2BR) has 6 rooms totalling 58 square metres. Building footprint 131 square metres; open space 220 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 0.74, daylight 0.28, privacy 0.83, circulation 0.62, carbon 0.73, cost 0.10.
