Plan drawing of a triplex on a 15.9 by 19.8 metre lot, 2 storeys, 3 dwellings, 20 rooms. Dwelling U0 (2BR) has 6 rooms totalling 56 square metres. Dwelling U1 (2BR) has 6 rooms totalling 58 square metres. Dwelling U2 (2BR) has 6 rooms totalling 113 square metres. Building footprint 123 square metres; open space 190 square metres. This design is infeasible; failing categories: bad proportion, insufficient area. Objective scores, higher is better: density 0.99, daylight 0.58, privacy 0.82, circulation 0.63, carbon 0.77, cost 0.31.
