I'm not a fan of pinnacles and funny hats and such, FYI. I'm just noting that concerns re: architectural design shouldn't evaporate at level [insert today's magic number here]. Every building taller than four or five floors should have some sort of completion at the top, some stepping back and/or distinguishing of the highest levels, etc. The more prominent that a building is going to be, the more effort we should expect re: a refined appearance at the very top.
Sometimes I think Victoria's rules are intended to present highrise buildings in the most unflattering light. A self-confirming hang-up. "See? We told you it was going to look like ***."
