Plan drawing of a rowhouse on a 22.2 by 26.7 metre lot, 2 storeys, 3 dwellings, 27 rooms. Dwelling U0 (2BR) has 9 rooms totalling 115 square metres. Dwelling U1 (2BR) has 9 rooms totalling 133 square metres. Dwelling U2 (2BR) has 9 rooms totalling 191 square metres. Building footprint 219 square metres; open space 356 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.67, daylight 0.75, privacy 0.92, circulation 0.50, carbon 0.85, cost 0.62.
