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 35 square metres. Dwelling U1 (1BR) has 5 rooms totalling 50 square metres. Dwelling U2 (1BR) has 5 rooms totalling 92 square metres. Dwelling U3 (1BR) has 5 rooms totalling 92 square metres. Dwelling U4 (2BR) has 6 rooms totalling 85 square metres. Building footprint 197 square metres; open space 334 square metres. This design is infeasible; failing categories: bad proportion, no street access, open space failure. Objective scores, higher is better: density 0.71, daylight 0.55, privacy 0.80, circulation 0.63, carbon 0.75, cost 0.24.
