Plan drawing of a rowhouse on a 18.5 by 25.0 metre lot, 2 storeys, 3 dwellings, 27 rooms. Dwelling U0 (2BR) has 9 rooms totalling 115 square metres. Dwelling U1 (2BR) has 9 rooms totalling 138 square metres. Dwelling U2 (2BR) has 9 rooms totalling 115 square metres. Building footprint 184 square metres; open space 276 square metres. This design is infeasible; failing categories: bad proportion. Objective scores, higher is better: density 0.96, daylight 0.50, privacy 0.85, circulation 0.45, carbon 0.83, cost 0.43.
