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 74 square metres. Dwelling U1 (3BR) has 11 rooms totalling 157 square metres. Dwelling U2 (2BR) has 9 rooms totalling 113 square metres. Building footprint 172 square metres; open space 299 square metres. This design is infeasible; failing categories: bad proportion, daylight failure, insufficient area. Objective scores, higher is better: density 0.62, daylight 0.45, privacy 0.88, circulation 0.46, carbon 0.81, cost 0.37.
