Plan drawing of a rowhouse on a 18.3 by 25.5 metre lot, 2 storeys, 3 dwellings, 29 rooms. Dwelling U0 (2BR) has 9 rooms totalling 102 square metres. Dwelling U1 (3BR) has 11 rooms totalling 166 square metres. Dwelling U2 (2BR) has 9 rooms totalling 98 square metres. Building footprint 183 square metres; open space 284 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, daylight failure, insufficient area. Objective scores, higher is better: density 0.69, daylight 0.44, privacy 0.86, circulation 0.45, carbon 0.82, cost 0.37.
