When I get my own place, my first and only must-haves are windows and floor-to-ceiling bookshelves. Not a bed, not a Sub-Zero, but windows and bookshelves:
Fitzhugh Karol & Lyndsay Caleo's beautiful (I'd call it perfect) brownstone. See Design*Sponge for the full set of pictures.
Another favorite is this still from Scott Engler’s house, shot by Melissa Kaseman (via Design Sponge). One day, man, one day.
