Plan drawing of a courtyard on a 19.3 by 26.8 metre lot, 2 storeys, 5 dwellings, 27 rooms. Dwelling U0 (studio) has 4 rooms totalling 31 square metres. Dwelling U1 (1BR) has 5 rooms totalling 40 square metres. Dwelling U2 (1BR) has 5 rooms totalling 47 square metres. Dwelling U3 (1BR) has 5 rooms totalling 47 square metres. Dwelling U4 (2BR) has 6 rooms totalling 71 square metres. Building footprint 152 square metres; open space 368 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 0.42, daylight 0.50, privacy 0.77, circulation 0.49, carbon 0.67, cost 0.06.
