Location: Knoxville, Tenn.
The Skinny: As one of the great Southern manufacturing cities, Knoxville is rich with architectural history, so it's a pity the builders of this riverside monstrosity had to cross an ocean for their inspiration. Villa Collina measures a cavernous 32,000 square feet, most of which is chock full of questionable design choices. For our money, the worst offender is the purple sitting room (above), which borders on the near-inconceivable. That's not to say the house doesn't have some impressive features—like a duo of heated swimming pools, an elevator, a seven-car garage—but they'd probably all look better in black and white.
