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 33 square metres. Dwelling U1 (1BR) has 5 rooms totalling 45 square metres. Dwelling U2 (1BR) has 5 rooms totalling 57 square metres. Dwelling U3 (1BR) has 5 rooms totalling 57 square metres. Dwelling U4 (2BR) has 6 rooms totalling 78 square metres. Building footprint 174 square metres; open space 308 square metres. This design is infeasible; failing categories: bad proportion, insufficient area. Objective scores, higher is better: density 0.60, daylight 0.47, privacy 0.82, circulation 0.52, carbon 0.71, cost 0.20.
