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 45 square metres. Dwelling U1 (1BR) has 5 rooms totalling 33 square metres. Dwelling U2 (2BR) has 6 rooms totalling 78 square metres. Building footprint 88 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 0.88, daylight 0.32, privacy 0.80, circulation 0.60, carbon 0.70, cost 0.27.
