Plan drawing of a rowhouse on a 19.9 by 22.1 metre lot, 2 storeys, 3 dwellings, 29 rooms. Dwelling U0 (2BR) has 9 rooms totalling 70 square metres. Dwelling U1 (3BR) has 11 rooms totalling 119 square metres. Dwelling U2 (2BR) has 9 rooms totalling 95 square metres. Building footprint 142 square metres; open space 300 square metres. This design is infeasible; failing categories: bad proportion. Objective scores, higher is better: density 0.62, daylight 0.64, privacy 0.90, circulation 0.56, carbon 0.76, cost 0.17.
