Plan drawing of a rowhouse on a 27.0 by 31.4 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 214 square metres. Dwelling U1 (2BR) has 9 rooms totalling 181 square metres. Dwelling U2 (2BR) has 9 rooms totalling 170 square metres. Dwelling U3 (2BR) has 9 rooms totalling 159 square metres. Building footprint 362 square metres; open space 490 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.69, daylight 0.56, privacy 0.92, circulation 0.46, carbon 0.91, cost 0.75.
