Plan drawing of a rowhouse on a 25.5 by 27.5 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 107 square metres. Dwelling U1 (2BR) has 9 rooms totalling 121 square metres. Dwelling U2 (2BR) has 9 rooms totalling 121 square metres. Dwelling U3 (2BR) has 9 rooms totalling 101 square metres. Building footprint 225 square metres; open space 481 square metres. This design is infeasible; failing categories: bad proportion. Objective scores, higher is better: density 0.50, daylight 0.59, privacy 0.85, circulation 0.46, carbon 0.82, cost 0.36.
