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 81 square metres. Dwelling U1 (1BR) has 5 rooms totalling 77 square metres. Dwelling U2 (2BR) has 6 rooms totalling 158 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 0.58, privacy 0.78, circulation 0.63, carbon 0.84, cost 0.78.
