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 3 square metres. Dwelling U1 (2BR) has 6 rooms totalling 3 square metres. Dwelling U2 (2BR) has 6 rooms totalling 6 square metres. Building footprint 82 square metres; open space 239 square metres. This design is infeasible; failing categories: invalid geometry. Objective scores, higher is better: density 0.43, daylight 0.10, privacy 0.77, circulation 0.38, carbon 0.71, cost 0.00.
