The gates are an unexpected design flourish, and refer to gates/ wrought iron work that often were part of traditional Toronto buildings built before modernism took root. (Take a walk just around the corner, you will see examples) They are at once traditionally detailed, yet also finished with graphic tracery cut by a cnc router, so bring them back to today so to speak, without being unduly historicist. The unusual juxtaposition draws attention to the residential entry. I like them.
A far more eloquent way of describing what I think: they shouldn't work, but they do.
And the way that they stand out definitely brings some drama and glamour to the entrance. Highly original and well executed.
