Plan drawing of a rowhouse on a 20.7 by 22.5 metre lot, 2 storeys, 3 dwellings, 29 rooms. Dwelling U0 (2BR) has 9 rooms totalling 89 square metres. Dwelling U1 (3BR) has 11 rooms totalling 112 square metres. Dwelling U2 (2BR) has 9 rooms totalling 98 square metres. Building footprint 149 square metres; open space 314 square metres. This design is infeasible; failing categories: bad proportion, daylight failure, insufficient area, no street access. Objective scores, higher is better: density 0.56, daylight 0.59, privacy 0.91, circulation 0.54, carbon 0.77, cost 0.16.
