Plan drawing of a triplex on a 16.8 by 22.7 metre lot, 2 storeys, 3 dwellings, 18 rooms. Dwelling U0 (1BR) has 5 rooms totalling 47 square metres. Dwelling U1 (1BR) has 5 rooms totalling 58 square metres. Dwelling U2 (2BR) has 6 rooms totalling 105 square metres. Building footprint 124 square metres; open space 262 square metres. This design is infeasible; failing categories: bad proportion, no street access. Objective scores, higher is better: density 0.54, daylight 0.78, privacy 0.78, circulation 0.56, carbon 0.78, cost 0.26.
