Plan drawing of a triplex on a 13.2 by 21.0 metre lot, 2 storeys, 3 dwellings, 17 rooms. Dwelling U0 (studio) has 4 rooms totalling 44 square metres. Dwelling U1 (1BR) has 5 rooms totalling 54 square metres. Dwelling U2 (2BR) has 6 rooms totalling 97 square metres. Building footprint 119 square metres; open space 154 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.99, daylight 0.29, privacy 0.77, circulation 0.57, carbon 0.78, cost 0.44.
