Plan drawing of a fourplex on a 14.4 by 39.3 metre lot, 2 storeys, 4 dwellings, 26 rooms. Dwelling U0 (2BR) has 6 rooms totalling 143 square metres. Dwelling U1 (2BR) has 6 rooms totalling 65 square metres. Dwelling U2 (2BR) has 6 rooms totalling 122 square metres. Dwelling U3 (2BR) has 6 rooms totalling 87 square metres. Building footprint 227 square metres; open space 345 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.66, daylight 0.46, privacy 0.86, circulation 0.62, carbon 0.84, cost 0.67.
