Plan drawing of a courtyard on a 16.2 by 25.5 metre lot, 2 storeys, 4 dwellings, 25 rooms. Dwelling U0 (1BR) has 5 rooms totalling 63 square metres. Dwelling U1 (2BR) has 6 rooms totalling 63 square metres. Dwelling U2 (2BR) has 6 rooms totalling 63 square metres. Dwelling U3 (2BR) has 6 rooms totalling 63 square metres. Building footprint 167 square metres; open space 242 square metres. This design is infeasible; failing categories: bad proportion, daylight failure, insufficient area, open space failure. Objective scores, higher is better: density 0.85, daylight 0.42, privacy 0.79, circulation 0.50, carbon 0.74, cost 0.27.
