Plan drawing of a courtyard on a 21.1 by 25.6 metre lot, 2 storeys, 5 dwellings, 27 rooms. Dwelling U0 (studio) has 4 rooms totalling 27 square metres. Dwelling U1 (1BR) has 5 rooms totalling 47 square metres. Dwelling U2 (1BR) has 5 rooms totalling 42 square metres. Dwelling U3 (1BR) has 5 rooms totalling 47 square metres. Dwelling U4 (2BR) has 6 rooms totalling 68 square metres. Building footprint 141 square metres; open space 386 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 0.29, daylight 0.45, privacy 0.77, circulation 0.55, carbon 0.65, cost 0.00.
