Plan drawing of a courtyard on a 16.2 by 25.5 metre lot, 2 storeys, 4 dwellings, 25 rooms. Dwelling U0 (1BR) has 5 rooms totalling 45 square metres. Dwelling U1 (2BR) has 6 rooms totalling 59 square metres. Dwelling U2 (2BR) has 6 rooms totalling 45 square metres. Dwelling U3 (2BR) has 6 rooms totalling 59 square metres. Building footprint 121 square metres; open space 284 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion, daylight failure, insufficient area, no street access. Objective scores, higher is better: density 0.47, daylight 0.34, privacy 0.80, circulation 0.57, carbon 0.61, cost 0.00.
