Plan drawing of a triplex on a 13.5 by 27.4 metre lot, 2 storeys, 3 dwellings, 17 rooms. Dwelling U0 (studio) has 4 rooms totalling 53 square metres. Dwelling U1 (1BR) has 5 rooms totalling 64 square metres. Dwelling U2 (2BR) has 6 rooms totalling 116 square metres. Building footprint 126 square metres; open space 247 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.67, daylight 0.41, privacy 0.92, circulation 0.62, carbon 0.79, cost 0.41.
