Plan drawing of a rowhouse on a 18.3 by 25.5 metre lot, 2 storeys, 3 dwellings, 29 rooms. Dwelling U0 (2BR) has 9 rooms totalling 85 square metres. Dwelling U1 (3BR) has 11 rooms totalling 138 square metres. Dwelling U2 (2BR) has 9 rooms totalling 199 square metres. Building footprint 211 square metres; open space 262 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.88, daylight 0.49, privacy 0.93, circulation 0.48, carbon 0.84, cost 0.51.
