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 72 square metres. Dwelling U1 (1BR) has 5 rooms totalling 85 square metres. Dwelling U2 (2BR) has 6 rooms totalling 74 square metres. Dwelling U3 (2BR) has 6 rooms totalling 83 square metres. Building footprint 178 square metres; open space 213 square metres. This design is infeasible; failing categories: adjacency violation. Objective scores, higher is better: density 0.95, daylight 0.40, privacy 0.84, circulation 0.55, carbon 0.81, cost 0.50.
