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 50 square metres. Dwelling U1 (1BR) has 5 rooms totalling 75 square metres. Dwelling U2 (2BR) has 6 rooms totalling 125 square metres. Building footprint 177 square metres; open space 207 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.56, privacy 0.83, circulation 0.52, carbon 0.85, cost 0.70.
