Plan drawing of a courtyard on a 19.9 by 25.6 metre lot, 2 storeys, 4 dwellings, 25 rooms. Dwelling U0 (1BR) has 5 rooms totalling 91 square metres. Dwelling U1 (2BR) has 6 rooms totalling 84 square metres. Dwelling U2 (2BR) has 6 rooms totalling 91 square metres. Dwelling U3 (2BR) has 6 rooms totalling 84 square metres. Building footprint 198 square metres; open space 317 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.77, daylight 0.61, privacy 0.77, circulation 0.66, carbon 0.76, cost 0.55.
