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 60 square metres. Dwelling U1 (1BR) has 5 rooms totalling 67 square metres. Dwelling U2 (2BR) has 6 rooms totalling 63 square metres. Dwelling U3 (2BR) has 6 rooms totalling 63 square metres. Building footprint 140 square metres; open space 146 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, daylight failure, no street access. Objective scores, higher is better: density 1.00, daylight 0.25, privacy 0.78, circulation 0.66, carbon 0.77, cost 0.38.
