Plan drawing of a rowhouse on a 24.4 by 28.2 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 140 square metres. Dwelling U1 (2BR) has 9 rooms totalling 150 square metres. Dwelling U2 (2BR) has 9 rooms totalling 167 square metres. Dwelling U3 (2BR) has 9 rooms totalling 162 square metres. Building footprint 310 square metres; open space 378 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.99, daylight 0.62, privacy 0.89, circulation 0.46, carbon 0.88, cost 0.63.
