Plan drawing of a courtyard on a 17.3 by 28.1 metre lot, 2 storeys, 5 dwellings, 27 rooms. Dwelling U0 (studio) has 4 rooms totalling 27 square metres. Dwelling U1 (1BR) has 5 rooms totalling 42 square metres. Dwelling U2 (1BR) has 5 rooms totalling 35 square metres. Dwelling U3 (1BR) has 5 rooms totalling 42 square metres. Dwelling U4 (2BR) has 6 rooms totalling 62 square metres. Building footprint 133 square metres; open space 352 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, daylight failure, insufficient area, no street access, open space failure. Objective scores, higher is better: density 0.44, daylight 0.43, privacy 0.80, circulation 0.51, carbon 0.63, cost 0.00.
