Anyone who's ever lived in New York City can tell you that space is at a premium. With sky-high rent and decreasing square footage, the cost of living in New York is among the highest in the world. That's why the work of masterminds like Graham Hill should come as no surprise. With some seriously clever design work, he managed to turn a 420-square-foot apartment into a living space with five rooms. Oh, and if you want it, it'll run you about a million bucks. He draws apt comparisons between this apartment and a Swiss army knife, and when you see what happens when he starts rearranging the space, you'll totally understand why. Hill dropped $287,000 and invested $365,000 into the renovation process, and we can see why this dwelling costs a pretty penny. Even if it's way out of your price range, you have to admit that this is pretty amazing! Clever people can capitalize on just about anything.
