Plan drawing of a courtyard on a 19.2 by 24.8 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 54 square metres. Dwelling U1 (1BR) has 5 rooms totalling 68 square metres. Dwelling U2 (2BR) has 6 rooms totalling 68 square metres. Dwelling U3 (2BR) has 6 rooms totalling 54 square metres. Building footprint 175 square metres; open space 300 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, insufficient area, no street access. Objective scores, higher is better: density 0.48, daylight 0.51, privacy 0.78, circulation 0.53, carbon 0.75, cost 0.30.
