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 108 square metres. Dwelling U1 (2BR) has 9 rooms totalling 109 square metres. Dwelling U2 (2BR) has 9 rooms totalling 112 square metres. Building footprint 164 square metres; open space 294 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.80, daylight 0.50, privacy 0.86, circulation 0.48, carbon 0.81, cost 0.38.
