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 55 square metres. Dwelling U1 (2BR) has 6 rooms totalling 58 square metres. Dwelling U2 (2BR) has 6 rooms totalling 113 square metres. Building footprint 125 square metres; open space 242 square metres. This design is infeasible; failing categories: adjacency violation, daylight failure, insufficient area. Objective scores, higher is better: density 1.00, daylight 0.54, privacy 0.78, circulation 0.69, carbon 0.78, cost 0.40.
