Plan drawing of a fourplex on a 14.6 by 26.9 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 71 square metres. Dwelling U1 (1BR) has 5 rooms totalling 66 square metres. Dwelling U2 (2BR) has 6 rooms totalling 77 square metres. Dwelling U3 (2BR) has 6 rooms totalling 60 square metres. Building footprint 151 square metres; open space 248 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 0.67, daylight 0.50, privacy 0.84, circulation 0.66, carbon 0.78, cost 0.44.
