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 48 square metres. Dwelling U1 (2BR) has 6 rooms totalling 51 square metres. Dwelling U2 (2BR) has 6 rooms totalling 99 square metres. Building footprint 111 square metres; open space 200 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 0.85, daylight 0.52, privacy 0.85, circulation 0.61, carbon 0.75, cost 0.22.
