Plan drawing of a rowhouse on a 18.5 by 25.0 metre lot, 2 storeys, 3 dwellings, 27 rooms. Dwelling U0 (2BR) has 9 rooms totalling 111 square metres. Dwelling U1 (2BR) has 9 rooms totalling 81 square metres. Dwelling U2 (2BR) has 9 rooms totalling 98 square metres. Building footprint 145 square metres; open space 322 square metres. This design is infeasible; failing categories: bad proportion, insufficient area. Objective scores, higher is better: density 0.64, daylight 0.65, privacy 0.88, circulation 0.47, carbon 0.78, cost 0.16.
