Plan drawing of a rowhouse on a 19.9 by 22.1 metre lot, 2 storeys, 3 dwellings, 29 rooms. Dwelling U0 (2BR) has 9 rooms totalling 99 square metres. Dwelling U1 (3BR) has 11 rooms totalling 152 square metres. Dwelling U2 (2BR) has 9 rooms totalling 95 square metres. Building footprint 173 square metres; open space 270 square metres. This design is infeasible; failing categories: adjacency violation, bad proportion. Objective scores, higher is better: density 0.88, daylight 0.56, privacy 0.86, circulation 0.46, carbon 0.81, cost 0.32.
Objective vector
Proxy scores in [0, 1], higher is better. Kept as a vector; there is no overall score.
