Plan drawing of a triplex on a 15.9 by 25.9 metre lot, 2 storeys, 3 dwellings, 20 rooms. Dwelling U0 (2BR) has 6 rooms totalling 68 square metres. Dwelling U1 (2BR) has 6 rooms totalling 75 square metres. Dwelling U2 (2BR) has 6 rooms totalling 143 square metres. Building footprint 155 square metres; open space 258 square metres. This design is infeasible; failing categories: bad proportion, daylight failure. Objective scores, higher is better: density 0.51, daylight 0.35, privacy 0.88, circulation 0.64, carbon 0.81, cost 0.49.
