Plan drawing of a rowhouse on a 29.5 by 30.6 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 162 square metres. Dwelling U1 (2BR) has 9 rooms totalling 133 square metres. Dwelling U2 (2BR) has 9 rooms totalling 172 square metres. Dwelling U3 (2BR) has 9 rooms totalling 180 square metres. Building footprint 324 square metres; open space 577 square metres. This design is infeasible; failing categories: bad proportion, daylight failure, no street access. Objective scores, higher is better: density 0.49, daylight 0.67, privacy 0.88, circulation 0.54, carbon 0.89, cost 0.61.
