Plan drawing of a fourplex on a 14.6 by 27.0 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 61 square metres. Dwelling U1 (1BR) has 5 rooms totalling 66 square metres. Dwelling U2 (2BR) has 6 rooms totalling 65 square metres. Dwelling U3 (2BR) has 6 rooms totalling 62 square metres. Building footprint 156 square metres; open space 232 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 0.77, daylight 0.29, privacy 0.83, circulation 0.52, carbon 0.80, cost 0.37.
