Plan drawing of a courtyard on a 21.8 by 22.2 metre lot, 2 storeys, 5 dwellings, 27 rooms. Dwelling U0 (studio) has 4 rooms totalling 29 square metres. Dwelling U1 (1BR) has 5 rooms totalling 41 square metres. Dwelling U2 (1BR) has 5 rooms totalling 48 square metres. Dwelling U3 (1BR) has 5 rooms totalling 48 square metres. Dwelling U4 (2BR) has 6 rooms totalling 70 square metres. Building footprint 162 square metres; open space 323 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, daylight failure, insufficient area, no street access. Objective scores, higher is better: density 0.52, daylight 0.44, privacy 0.82, circulation 0.51, carbon 0.71, cost 0.10.
