Plan drawing of a courtyard on a 21.7 by 26.3 metre lot, 2 storeys, 4 dwellings, 25 rooms. Dwelling U0 (1BR) has 5 rooms totalling 59 square metres. Dwelling U1 (2BR) has 6 rooms totalling 72 square metres. Dwelling U2 (2BR) has 6 rooms totalling 72 square metres. Dwelling U3 (2BR) has 6 rooms totalling 59 square metres. Building footprint 165 square metres; open space 397 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, insufficient area, no street access. Objective scores, higher is better: density 0.40, daylight 0.66, privacy 0.81, circulation 0.51, carbon 0.71, cost 0.16.
