Plan drawing of a rowhouse on a 25.5 by 27.5 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 137 square metres. Dwelling U1 (2BR) has 9 rooms totalling 132 square metres. Dwelling U2 (2BR) has 9 rooms totalling 144 square metres. Dwelling U3 (2BR) has 9 rooms totalling 114 square metres. Building footprint 263 square metres; open space 435 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, no street access. Objective scores, higher is better: density 0.68, daylight 0.60, privacy 0.89, circulation 0.53, carbon 0.86, cost 0.52.
