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 68 square metres. Dwelling U1 (2BR) has 9 rooms totalling 82 square metres. Dwelling U2 (2BR) has 9 rooms totalling 128 square metres. Building footprint 139 square metres; open space 322 square metres. This design is infeasible; failing categories: bad proportion, daylight failure, no street access. Objective scores, higher is better: density 0.59, daylight 0.63, privacy 0.88, circulation 0.53, carbon 0.77, cost 0.04.
