Plan drawing of a fourplex on a 15.0 by 24.2 metre lot, 2 storeys, 4 dwellings, 22 rooms. Dwelling U0 (studio) has 4 rooms totalling 72 square metres. Dwelling U1 (1BR) has 5 rooms totalling 66 square metres. Dwelling U2 (1BR) has 5 rooms totalling 66 square metres. Dwelling U3 (2BR) has 6 rooms totalling 71 square metres. Building footprint 173 square metres; open space 180 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.89, daylight 0.42, privacy 0.70, circulation 0.55, carbon 0.81, cost 0.45.
