Plan drawing of a courtyard on a 19.7 by 27.7 metre lot, 2 storeys, 5 dwellings, 27 rooms. Dwelling U0 (studio) has 4 rooms totalling 44 square metres. Dwelling U1 (1BR) has 5 rooms totalling 59 square metres. Dwelling U2 (1BR) has 5 rooms totalling 62 square metres. Dwelling U3 (1BR) has 5 rooms totalling 62 square metres. Dwelling U4 (2BR) has 6 rooms totalling 103 square metres. Building footprint 237 square metres; open space 304 square metres. This design is infeasible; failing categories: open space failure. Objective scores, higher is better: density 0.84, daylight 0.55, privacy 0.81, circulation 0.49, carbon 0.81, cost 0.61.
