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 84 square metres. Dwelling U1 (1BR) has 5 rooms totalling 97 square metres. Dwelling U2 (2BR) has 6 rooms totalling 97 square metres. Dwelling U3 (2BR) has 6 rooms totalling 84 square metres. Building footprint 218 square metres; open space 260 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.72, daylight 0.55, privacy 0.86, circulation 0.51, carbon 0.78, cost 0.45.
