Balconies are a real practical challenge in Boston. We have the highest average wind speed of any major city in the country. Balconies on a high rise become a source of deadly projectiles, if not carefully managed. Managers of high rise buildings are terrified of the liability associated with flying furniture, etc. The penthouse units in my building (floor 22) have balconies, and they get regular inspections to be sure all "loose items" are tied down to the building anchors (provided). And we get notices of high wind conditions to warn about flying objects.
Not as much of an issue in a mid-rise like Clippership, so nice to see there.
