Plan drawing of a courtyard on a 17.3 by 28.1 metre lot, 2 storeys, 5 dwellings, 27 rooms. Dwelling U0 (studio) has 4 rooms totalling 32 square metres. Dwelling U1 (1BR) has 5 rooms totalling 59 square metres. Dwelling U2 (1BR) has 5 rooms totalling 47 square metres. Dwelling U3 (1BR) has 5 rooms totalling 59 square metres. Dwelling U4 (2BR) has 6 rooms totalling 79 square metres. Building footprint 159 square metres; open space 334 square metres. This design is infeasible; failing categories: bad proportion, insufficient area, open space failure. Objective scores, higher is better: density 0.63, daylight 0.39, privacy 0.76, circulation 0.52, carbon 0.69, cost 0.06.
