Plan drawing of a triplex on a 15.9 by 25.9 metre lot, 2 storeys, 3 dwellings, 20 rooms. Dwelling U0 (2BR) has 6 rooms totalling 78 square metres. Dwelling U1 (2BR) has 6 rooms totalling 94 square metres. Dwelling U2 (2BR) has 6 rooms totalling 172 square metres. Building footprint 187 square metres; open space 232 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.74, daylight 0.39, privacy 0.89, circulation 0.66, carbon 0.85, cost 0.67.
