Plan drawing of a courtyard on a 19.2 by 24.2 metre lot, 2 storeys, 4 dwellings, 25 rooms. Dwelling U0 (1BR) has 5 rooms totalling 48 square metres. Dwelling U1 (2BR) has 6 rooms totalling 62 square metres. Dwelling U2 (2BR) has 6 rooms totalling 48 square metres. Dwelling U3 (2BR) has 6 rooms totalling 62 square metres. Building footprint 129 square metres; open space 326 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, insufficient area, no street access. Objective scores, higher is better: density 0.53, daylight 0.51, privacy 0.83, circulation 0.57, carbon 0.64, cost 0.07.
