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 33 square metres. Dwelling U1 (1BR) has 5 rooms totalling 62 square metres. Dwelling U2 (1BR) has 5 rooms totalling 55 square metres. Dwelling U3 (1BR) has 5 rooms totalling 62 square metres. Dwelling U4 (2BR) has 6 rooms totalling 88 square metres. Building footprint 179 square metres; open space 354 square metres. This design is infeasible; failing categories: insufficient area. Objective scores, higher is better: density 0.52, daylight 0.52, privacy 0.80, circulation 0.58, carbon 0.72, cost 0.19.
