Plan drawing of a courtyard on a 21.7 by 27.8 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 55 square metres. Dwelling U1 (1BR) has 5 rooms totalling 71 square metres. Dwelling U2 (2BR) has 6 rooms totalling 71 square metres. Dwelling U3 (2BR) has 6 rooms totalling 55 square metres. Building footprint 171 square metres; open space 432 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, insufficient area. Objective scores, higher is better: density 0.35, daylight 0.70, privacy 0.86, circulation 0.50, carbon 0.72, cost 0.35.
