Plan drawing of a adu pair on a 12.8 by 23.5 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (2BR) has 6 rooms totalling 116 square metres. Dwelling U1 (1BR) has 5 rooms totalling 116 square metres. Building footprint 128 square metres; open space 180 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.97, daylight 0.48, privacy 0.88, circulation 0.70, carbon 0.82, cost 0.72.
