Plan drawing of a rowhouse on a 25.0 by 30.3 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 158 square metres. Dwelling U1 (2BR) has 9 rooms totalling 105 square metres. Dwelling U2 (2BR) has 9 rooms totalling 105 square metres. Dwelling U3 (2BR) has 9 rooms totalling 134 square metres. Building footprint 251 square metres; open space 509 square metres. This design is infeasible; failing categories: bad proportion, no street access. Objective scores, higher is better: density 0.51, daylight 0.68, privacy 0.89, circulation 0.53, carbon 0.85, cost 0.55.
