Bart Prince walks through a "pivot door" to enter his studio from the outside. The design is one of countless ways the world-renowned Albuquerque architect upends classic notions of how a house should look and function. "I didn't want it to just be a door," he said. "It's more of a panel designed to be a piece of the wall. When you push it open, it becomes a sculptural element you can see from both sides." Prince is as normal a man as you'll meet, but the homes he creates seem far-out. Wacky. But what's truly wacky is how much sense they make.
