Plan drawing of a fourplex on a 12.0 by 29.2 metre lot, 2 storeys, 4 dwellings, 26 rooms. Dwelling U0 (2BR) has 6 rooms totalling 68 square metres. Dwelling U1 (2BR) has 6 rooms totalling 70 square metres. Dwelling U2 (2BR) has 6 rooms totalling 66 square metres. Dwelling U3 (2BR) has 6 rooms totalling 72 square metres. Building footprint 149 square metres; open space 195 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.92, daylight 0.42, privacy 0.78, circulation 0.69, carbon 0.78, cost 0.54.
