Plan drawing of a triplex on a 14.9 by 24.4 metre lot, 2 storeys, 3 dwellings, 20 rooms. Dwelling U0 (2BR) has 6 rooms totalling 59 square metres. Dwelling U1 (2BR) has 6 rooms totalling 50 square metres. Dwelling U2 (2BR) has 6 rooms totalling 110 square metres. Building footprint 123 square metres; open space 248 square metres. This design is infeasible; failing categories: bad proportion, daylight failure, insufficient area. Objective scores, higher is better: density 0.97, daylight 0.53, privacy 0.89, circulation 0.59, carbon 0.77, cost 0.38.
