Plan drawing of a rowhouse on a 19.9 by 22.1 metre lot, 2 storeys, 3 dwellings, 29 rooms. Dwelling U0 (2BR) has 9 rooms totalling 70 square metres. Dwelling U1 (3BR) has 11 rooms totalling 142 square metres. Dwelling U2 (2BR) has 9 rooms totalling 82 square metres. Building footprint 147 square metres; open space 293 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, insufficient area. Objective scores, higher is better: density 0.67, daylight 0.63, privacy 0.89, circulation 0.50, carbon 0.77, cost 0.21.
