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 114 square metres. Dwelling U1 (3BR) has 11 rooms totalling 169 square metres. Dwelling U2 (2BR) has 9 rooms totalling 79 square metres. Building footprint 181 square metres; open space 280 square metres. This design is infeasible; failing categories: daylight failure, no street access. Objective scores, higher is better: density 0.80, daylight 0.39, privacy 0.86, circulation 0.46, carbon 0.82, cost 0.46.
