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 95 square metres. Dwelling U1 (3BR) has 11 rooms totalling 189 square metres. Dwelling U2 (2BR) has 9 rooms totalling 99 square metres. Building footprint 191 square metres; open space 272 square metres. This design is infeasible; failing categories: no street access. Objective scores, higher is better: density 0.87, daylight 0.65, privacy 0.89, circulation 0.50, carbon 0.83, cost 0.41.
