Plan drawing of a triplex on a 16.3 by 19.4 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 55 square metres. Dwelling U2 (2BR) has 6 rooms totalling 110 square metres. Building footprint 121 square metres; open space 198 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, daylight failure, insufficient area, no street access. Objective scores, higher is better: density 0.89, daylight 0.58, privacy 0.85, circulation 0.65, carbon 0.77, cost 0.30.
