Plan drawing of a courtyard on a 19.3 by 26.8 metre lot, 2 storeys, 5 dwellings, 27 rooms. Dwelling U0 (studio) has 4 rooms totalling 72 square metres. Dwelling U1 (1BR) has 5 rooms totalling 57 square metres. Dwelling U2 (1BR) has 5 rooms totalling 56 square metres. Dwelling U3 (1BR) has 5 rooms totalling 56 square metres. Dwelling U4 (2BR) has 6 rooms totalling 129 square metres. Building footprint 238 square metres; open space 292 square metres. This design is infeasible; failing categories: bad proportion, open space failure. Objective scores, higher is better: density 0.96, daylight 0.37, privacy 0.85, circulation 0.52, carbon 0.81, cost 0.52.
