Plan drawing of a rowhouse on a 18.5 by 25.0 metre lot, 2 storeys, 3 dwellings, 27 rooms. Dwelling U0 (2BR) has 9 rooms totalling 193 square metres. Dwelling U1 (2BR) has 9 rooms totalling 90 square metres. Dwelling U2 (2BR) has 9 rooms totalling 95 square metres. Building footprint 189 square metres; open space 270 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.81, privacy 0.92, circulation 0.47, carbon 0.83, cost 0.52.
