The only problem was that it would be hard for the apartments in the north tower to have the same views as those in the south one, which is closer to the water, unless something unusual occurred. By swiveling the floors two-thirds of the way up and giving the south tower a square footprint that was smaller than that of the rectangular north one, the architects could provide spectacular views to almost all the occupants. (Only seven smaller units don’t have water views.) In addition, open-plan apartments with 12-foot-high ceilings make you feel as if you are sailing on a large yacht. And when you step onto one of the deep, cantilevered balconies that can extend out as much as 12 feet, it’s as if you are perched on a tall mast overlooking the marina and the bay beyond.
