Plan drawing of a fourplex on a 17.0 by 26.0 metre lot, 2 storeys, 4 dwellings, 26 rooms. Dwelling U0 (2BR) has 6 rooms totalling 73 square metres. Dwelling U1 (2BR) has 6 rooms totalling 74 square metres. Dwelling U2 (2BR) has 6 rooms totalling 72 square metres. Dwelling U3 (2BR) has 6 rooms totalling 76 square metres. Building footprint 166 square metres; open space 273 square metres. This design is infeasible; failing categories: daylight failure. Objective scores, higher is better: density 0.81, daylight 0.58, privacy 0.80, circulation 0.61, carbon 0.80, cost 0.45.
