Plan drawing of a triplex on a 16.0 by 22.4 metre lot, 2 storeys, 3 dwellings, 18 rooms. Dwelling U0 (1BR) has 5 rooms totalling 52 square metres. Dwelling U1 (1BR) has 5 rooms totalling 73 square metres. Dwelling U2 (2BR) has 6 rooms totalling 106 square metres. Building footprint 130 square metres; open space 230 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.83, daylight 0.77, privacy 0.78, circulation 0.75, carbon 0.73, cost 0.31.
