Plan drawing of a courtyard on a 21.7 by 21.6 metre lot, 2 storeys, 4 dwellings, 25 rooms. Dwelling U0 (1BR) has 5 rooms totalling 55 square metres. Dwelling U1 (2BR) has 6 rooms totalling 66 square metres. Dwelling U2 (2BR) has 6 rooms totalling 66 square metres. Dwelling U3 (2BR) has 6 rooms totalling 55 square metres. Building footprint 146 square metres; open space 323 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, insufficient area, no street access. Objective scores, higher is better: density 0.33, daylight 0.56, privacy 0.81, circulation 0.55, carbon 0.67, cost 0.14.
