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 32 square metres. Dwelling U1 (1BR) has 5 rooms totalling 48 square metres. Dwelling U2 (1BR) has 5 rooms totalling 96 square metres. Dwelling U3 (1BR) has 5 rooms totalling 96 square metres. Dwelling U4 (2BR) has 6 rooms totalling 80 square metres. Building footprint 198 square metres; open space 290 square metres. This design is infeasible; failing categories: bad proportion, insufficient area. Objective scores, higher is better: density 0.76, daylight 0.40, privacy 0.70, circulation 0.69, carbon 0.75, cost 0.42.
