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 113 square metres. Dwelling U1 (2BR) has 9 rooms totalling 109 square metres. Dwelling U2 (2BR) has 9 rooms totalling 82 square metres. Building footprint 152 square metres; open space 306 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.69, daylight 0.73, privacy 0.86, circulation 0.57, carbon 0.79, cost 0.42.
