Plan drawing of a triplex on a 14.1 by 21.5 metre lot, 2 storeys, 3 dwellings, 17 rooms. Dwelling U0 (studio) has 4 rooms totalling 37 square metres. Dwelling U1 (1BR) has 5 rooms totalling 77 square metres. Dwelling U2 (2BR) has 6 rooms totalling 114 square metres. Building footprint 128 square metres; open space 171 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.41, privacy 0.83, circulation 0.62, carbon 0.79, cost 0.49.
