Plan drawing of a triplex on a 15.8 by 20.8 metre lot, 2 storeys, 3 dwellings, 18 rooms. Dwelling U0 (1BR) has 5 rooms totalling 66 square metres. Dwelling U1 (1BR) has 5 rooms totalling 66 square metres. Dwelling U2 (2BR) has 6 rooms totalling 131 square metres. Building footprint 149 square metres; open space 186 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.53, privacy 0.76, circulation 0.64, carbon 0.81, cost 0.64.
