A "wall" of 50-storey buildings blocking the view from the escarpment to the harbour and vice versa would be something to energetically protest.

A forest of 20 and 30 storey towers (among quality mid-rises) with a few of 40, 50, or more would be interesting, whether viewed from the waterfront or the brow. Especially if they're standout designs. Signature towers should be the exception, if they're exceptional.

I think the market will dictate what heights are the debate of the day (30-35 floors seems to be the current standard) but there should not be any kind of restriction on a future new tallest or taller without taking the literal big picture into context.
