Plan drawing of a rowhouse on a 22.2 by 26.7 metre lot, 2 storeys, 3 dwellings, 27 rooms. Dwelling U0 (2BR) has 9 rooms totalling 123 square metres. Dwelling U1 (2BR) has 9 rooms totalling 93 square metres. Dwelling U2 (2BR) has 9 rooms totalling 179 square metres. Building footprint 198 square metres; open space 385 square metres. This design is infeasible; failing categories: bad proportion. Objective scores, higher is better: density 0.55, daylight 0.61, privacy 0.91, circulation 0.49, carbon 0.83, cost 0.43.
