Plan drawing of a courtyard on a 19.7 by 27.7 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 47 square metres. Dwelling U2 (1BR) has 5 rooms totalling 78 square metres. Dwelling U3 (1BR) has 5 rooms totalling 78 square metres. Dwelling U4 (2BR) has 6 rooms totalling 82 square metres. Building footprint 200 square metres; open space 340 square metres. This design is infeasible; failing categories: bad proportion. Objective scores, higher is better: density 0.63, daylight 0.52, privacy 0.82, circulation 0.50, carbon 0.75, cost 0.38.
