Plan drawing of a rowhouse on a 20.7 by 22.5 metre lot, 2 storeys, 3 dwellings, 29 rooms. Dwelling U0 (2BR) has 9 rooms totalling 82 square metres. Dwelling U1 (3BR) has 11 rooms totalling 183 square metres. Dwelling U2 (2BR) has 9 rooms totalling 83 square metres. Building footprint 174 square metres; open space 285 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.74, daylight 0.62, privacy 0.87, circulation 0.53, carbon 0.81, cost 0.38.
