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 30 square metres. Dwelling U1 (1BR) has 5 rooms totalling 51 square metres. Dwelling U2 (1BR) has 5 rooms totalling 58 square metres. Dwelling U3 (1BR) has 5 rooms totalling 58 square metres. Dwelling U4 (2BR) has 6 rooms totalling 82 square metres. Building footprint 167 square metres; open space 382 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 0.43, daylight 0.49, privacy 0.79, circulation 0.52, carbon 0.69, cost 0.14.
