Plan drawing of a adu pair on a 16.6 by 21.5 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (2BR) has 6 rooms totalling 74 square metres. Dwelling U1 (1BR) has 5 rooms totalling 74 square metres. Building footprint 126 square metres; open space 231 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.75, privacy 0.81, circulation 0.53, carbon 0.83, cost 0.60.
