Plan drawing of a courtyard on a 21.8 by 22.2 metre lot, 2 storeys, 5 dwellings, 27 rooms. Dwelling U0 (studio) has 4 rooms totalling 38 square metres. Dwelling U1 (1BR) has 5 rooms totalling 52 square metres. Dwelling U2 (1BR) has 5 rooms totalling 77 square metres. Dwelling U3 (1BR) has 5 rooms totalling 77 square metres. Dwelling U4 (2BR) has 6 rooms totalling 90 square metres. Building footprint 188 square metres; open space 300 square metres. This design is infeasible; failing categories: bad proportion, open space failure. Objective scores, higher is better: density 0.69, daylight 0.47, privacy 0.81, circulation 0.60, carbon 0.73, cost 0.32.
