Plan drawing of a rowhouse on a 27.0 by 31.4 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 139 square metres. Dwelling U1 (2BR) has 9 rooms totalling 181 square metres. Dwelling U2 (2BR) has 9 rooms totalling 131 square metres. Dwelling U3 (2BR) has 9 rooms totalling 213 square metres. Building footprint 332 square metres; open space 517 square metres. This design is infeasible; failing categories: bad proportion, no street access. Objective scores, higher is better: density 0.59, daylight 0.69, privacy 0.87, circulation 0.48, carbon 0.89, cost 0.67.
