Plan drawing of a triplex on a 16.4 by 19.0 metre lot, 2 storeys, 3 dwellings, 17 rooms. Dwelling U0 (studio) has 4 rooms totalling 49 square metres. Dwelling U1 (1BR) has 5 rooms totalling 58 square metres. Dwelling U2 (2BR) has 6 rooms totalling 107 square metres. Building footprint 122 square metres; open space 195 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.99, daylight 0.59, privacy 0.83, circulation 0.58, carbon 0.78, cost 0.39.
