Plan drawing of a courtyard on a 19.2 by 24.2 metre lot, 2 storeys, 4 dwellings, 25 rooms. Dwelling U0 (1BR) has 5 rooms totalling 76 square metres. Dwelling U1 (2BR) has 6 rooms totalling 64 square metres. Dwelling U2 (2BR) has 6 rooms totalling 76 square metres. Dwelling U3 (2BR) has 6 rooms totalling 64 square metres. Building footprint 159 square metres; open space 296 square metres. This design is infeasible; failing categories: open space failure. Objective scores, higher is better: density 0.79, daylight 0.47, privacy 0.77, circulation 0.64, carbon 0.71, cost 0.46.
