Plan drawing of a courtyard on a 21.1 by 25.6 metre lot, 2 storeys, 5 dwellings, 27 rooms. Dwelling U0 (studio) has 4 rooms totalling 34 square metres. Dwelling U1 (1BR) has 5 rooms totalling 73 square metres. Dwelling U2 (1BR) has 5 rooms totalling 46 square metres. Dwelling U3 (1BR) has 5 rooms totalling 73 square metres. Dwelling U4 (2BR) has 6 rooms totalling 80 square metres. Building footprint 197 square metres; open space 335 square metres. This design is infeasible; failing categories: bad proportion, no street access. Objective scores, higher is better: density 0.63, daylight 0.48, privacy 0.80, circulation 0.49, carbon 0.75, cost 0.29.
