Plan drawing of a rowhouse on a 20.7 by 22.5 metre lot, 2 storeys, 3 dwellings, 29 rooms. Dwelling U0 (2BR) has 9 rooms totalling 104 square metres. Dwelling U1 (3BR) has 11 rooms totalling 163 square metres. Dwelling U2 (2BR) has 9 rooms totalling 100 square metres. Building footprint 184 square metres; open space 280 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion. Objective scores, higher is better: density 0.82, daylight 0.42, privacy 0.86, circulation 0.45, carbon 0.82, cost 0.42.
Objective vector
Proxy scores in [0, 1], higher is better. Kept as a vector; there is no overall score.
