Plan drawing of a courtyard on a 21.8 by 22.2 metre lot, 2 storeys, 5 dwellings, 27 rooms. Dwelling U0 (studio) has 4 rooms totalling 35 square metres. Dwelling U1 (1BR) has 5 rooms totalling 50 square metres. Dwelling U2 (1BR) has 5 rooms totalling 65 square metres. Dwelling U3 (1BR) has 5 rooms totalling 65 square metres. Dwelling U4 (2BR) has 6 rooms totalling 85 square metres. Building footprint 184 square metres; open space 306 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, daylight failure. Objective scores, higher is better: density 0.67, daylight 0.44, privacy 0.75, circulation 0.53, carbon 0.73, cost 0.26.
