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 60 square metres. Dwelling U1 (2BR) has 6 rooms totalling 58 square metres. Dwelling U2 (2BR) has 6 rooms totalling 118 square metres. Building footprint 131 square metres; open space 187 square metres. This design is infeasible; failing categories: insufficient area. Objective scores, higher is better: density 1.00, daylight 0.59, privacy 0.83, circulation 0.68, carbon 0.79, cost 0.43.
