Plan drawing of a courtyard on a 21.7 by 27.8 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 117 square metres. Dwelling U1 (1BR) has 5 rooms totalling 114 square metres. Dwelling U2 (2BR) has 6 rooms totalling 114 square metres. Dwelling U3 (2BR) has 6 rooms totalling 117 square metres. Building footprint 254 square metres; open space 350 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.79, daylight 0.46, privacy 0.75, circulation 0.73, carbon 0.81, cost 0.73.
