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 77 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 77 square metres. Building footprint 259 square metres; open space 342 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.81, daylight 0.61, privacy 0.87, circulation 0.49, carbon 0.83, cost 0.76.
