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 94 square metres. Dwelling U1 (1BR) has 5 rooms totalling 116 square metres. Dwelling U2 (2BR) has 6 rooms totalling 116 square metres. Dwelling U3 (2BR) has 6 rooms totalling 94 square metres. Building footprint 272 square metres; open space 331 square metres. This design is infeasible; failing categories: open space failure. Objective scores, higher is better: density 0.88, daylight 0.50, privacy 0.79, circulation 0.52, carbon 0.84, cost 0.79.
