Plan drawing of a courtyard on a 21.7 by 26.3 metre lot, 2 storeys, 4 dwellings, 25 rooms. Dwelling U0 (1BR) has 5 rooms totalling 64 square metres. Dwelling U1 (2BR) has 6 rooms totalling 94 square metres. Dwelling U2 (2BR) has 6 rooms totalling 94 square metres. Dwelling U3 (2BR) has 6 rooms totalling 64 square metres. Building footprint 238 square metres; open space 331 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.81, daylight 0.66, privacy 0.87, circulation 0.50, carbon 0.82, cost 0.63.
