These windows are of course made more magnificent by their floor-to-ceiling nature, but they still only allow for light from one side, or two if you happen to be in a corner unit.
So, then I picture a single unit occupying an entire floor. Four sides of floor-to-ceiling windows! What luxury! Natural light from all sides! All the time!
But—where would I put my books? Bookshelves need walls to rest against. You can't just go putting a bookshelf in front of a window.
And—where would I hang my art? The creative minds of the world create so much wall-worthy art that I can barely frame it fast enough.
Maybe I don't need so many windows.
