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 178 square metres. Dwelling U1 (3BR) has 11 rooms totalling 168 square metres. Dwelling U2 (2BR) has 9 rooms totalling 76 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 0.89, daylight 0.44, privacy 0.90, circulation 0.47, carbon 0.85, cost 0.52.
