Plan drawing of a courtyard on a 19.9 by 25.6 metre lot, 2 storeys, 4 dwellings, 25 rooms. Dwelling U0 (1BR) has 5 rooms totalling 46 square metres. Dwelling U1 (2BR) has 6 rooms totalling 60 square metres. Dwelling U2 (2BR) has 6 rooms totalling 46 square metres. Dwelling U3 (2BR) has 6 rooms totalling 60 square metres. Building footprint 141 square metres; open space 368 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, insufficient area, no street access. Objective scores, higher is better: density 0.39, daylight 0.65, privacy 0.80, circulation 0.53, carbon 0.68, cost 0.02.
