Plan drawing of a rowhouse on a 24.4 by 28.2 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 120 square metres. Dwelling U1 (2BR) has 9 rooms totalling 114 square metres. Dwelling U2 (2BR) has 9 rooms totalling 121 square metres. Dwelling U3 (2BR) has 9 rooms totalling 118 square metres. Building footprint 236 square metres; open space 450 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.63, daylight 0.50, privacy 0.86, circulation 0.46, carbon 0.84, cost 0.45.
