Plan drawing of a courtyard on a 19.2 by 24.8 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 78 square metres. Dwelling U1 (1BR) has 5 rooms totalling 91 square metres. Dwelling U2 (2BR) has 6 rooms totalling 91 square metres. Dwelling U3 (2BR) has 6 rooms totalling 78 square metres. Building footprint 224 square metres; open space 248 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.76, daylight 0.53, privacy 0.83, circulation 0.52, carbon 0.80, cost 0.53.
