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 89 square metres. Dwelling U1 (2BR) has 6 rooms totalling 91 square metres. Dwelling U2 (2BR) has 6 rooms totalling 180 square metres. Building footprint 196 square metres; open space 215 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.79, daylight 0.37, privacy 0.85, circulation 0.64, carbon 0.86, cost 0.78.
