Plan drawing of a rowhouse on a 25.5 by 27.5 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 186 square metres. Dwelling U1 (2BR) has 9 rooms totalling 145 square metres. Dwelling U2 (2BR) has 9 rooms totalling 188 square metres. Dwelling U3 (2BR) has 9 rooms totalling 140 square metres. Building footprint 329 square metres; open space 365 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.99, daylight 0.64, privacy 0.88, circulation 0.52, carbon 0.89, cost 0.70.
