Plan drawing of a rowhouse on a 25.5 by 27.5 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 127 square metres. Dwelling U1 (2BR) has 9 rooms totalling 158 square metres. Dwelling U2 (2BR) has 9 rooms totalling 151 square metres. Dwelling U3 (2BR) has 9 rooms totalling 126 square metres. Building footprint 281 square metres; open space 428 square metres. This design is infeasible; failing categories: bad proportion. Objective scores, higher is better: density 0.77, daylight 0.51, privacy 0.83, circulation 0.47, carbon 0.87, cost 0.54.
