Plan drawing of a rowhouse on a 18.3 by 25.5 metre lot, 2 storeys, 3 dwellings, 29 rooms. Dwelling U0 (2BR) has 9 rooms totalling 66 square metres. Dwelling U1 (3BR) has 11 rooms totalling 192 square metres. Dwelling U2 (2BR) has 9 rooms totalling 94 square metres. Building footprint 176 square metres; open space 296 square metres. This design is infeasible; failing categories: bad proportion, daylight failure, insufficient area, no street access. Objective scores, higher is better: density 0.65, daylight 0.53, privacy 0.91, circulation 0.53, carbon 0.81, cost 0.33.
