Plan drawing of a rowhouse on a 25.0 by 30.3 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 148 square metres. Dwelling U1 (2BR) has 9 rooms totalling 184 square metres. Dwelling U2 (2BR) has 9 rooms totalling 173 square metres. Dwelling U3 (2BR) has 9 rooms totalling 141 square metres. Building footprint 323 square metres; open space 440 square metres. This design is infeasible; failing categories: bad proportion. Objective scores, higher is better: density 0.82, daylight 0.55, privacy 0.85, circulation 0.47, carbon 0.89, cost 0.74.
