Plan drawing of a adu pair on a 16.3 by 19.9 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (2BR) has 6 rooms totalling 85 square metres. Dwelling U1 (1BR) has 5 rooms totalling 85 square metres. Building footprint 133 square metres; open space 195 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.99, daylight 0.55, privacy 0.92, circulation 0.50, carbon 0.84, cost 0.64.
