Plan drawing of a courtyard on a 21.1 by 25.6 metre lot, 2 storeys, 5 dwellings, 27 rooms. Dwelling U0 (studio) has 4 rooms totalling 42 square metres. Dwelling U1 (1BR) has 5 rooms totalling 84 square metres. Dwelling U2 (1BR) has 5 rooms totalling 70 square metres. Dwelling U3 (1BR) has 5 rooms totalling 84 square metres. Dwelling U4 (2BR) has 6 rooms totalling 112 square metres. Building footprint 215 square metres; open space 323 square metres. This design is infeasible; failing categories: bad proportion, open space failure. Objective scores, higher is better: density 0.73, daylight 0.35, privacy 0.78, circulation 0.57, carbon 0.76, cost 0.43.
