Plan drawing of a fourplex on a 14.3 by 19.9 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 62 square metres. Dwelling U1 (1BR) has 5 rooms totalling 57 square metres. Dwelling U2 (2BR) has 6 rooms totalling 60 square metres. Dwelling U3 (2BR) has 6 rooms totalling 58 square metres. Building footprint 128 square metres; open space 164 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 0.87, daylight 0.31, privacy 0.86, circulation 0.65, carbon 0.75, cost 0.04.
