Plan drawing of a triplex on a 11.6 by 23.5 metre lot, 2 storeys, 3 dwellings, 18 rooms. Dwelling U0 (1BR) has 5 rooms totalling 42 square metres. Dwelling U1 (1BR) has 5 rooms totalling 38 square metres. Dwelling U2 (2BR) has 6 rooms totalling 80 square metres. Building footprint 89 square metres; open space 181 square metres. This design is infeasible; failing categories: bad proportion, daylight failure, insufficient area. Objective scores, higher is better: density 0.90, daylight 0.37, privacy 0.75, circulation 0.68, carbon 0.71, cost 0.28.
