Smallest House In The World For Sale

When I first heard about this house it was promoted as the Brooklyn, NY's smallest house.  I would like to see if anyone knows of something smaller.  It occupies what used to be a driveway, it's one bedroom, one bathroom and sits on a parcel of land 7.25 feet wide and 113.67 feet long. It's interior area is about 299 square feet.  It's for sale for $479,000 (or so I heard at first).  It's a bargain which includes a window air conditioner, a stach washer/ dryer and a small (what else) brick patio.  Truth is upon further investigation the house is actually in Toronto and couldn't sell at $179,000 though it was marketed as a bogus listing in NYC.  People were lining up for it at almost $500,000.  Alas...it was rented after it couldn't be sold.
