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 56 square metres. Dwelling U1 (1BR) has 5 rooms totalling 51 square metres. Dwelling U2 (2BR) has 6 rooms totalling 107 square metres. Building footprint 118 square metres; open space 266 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.49, daylight 0.71, privacy 0.90, circulation 0.57, carbon 0.77, cost 0.28.
