In the films the location was home to Harry's relatives the Dursleys, and was famously located at 4 Privet Drive, Little Whinging, Surrey. The real world address is 12 Picket Post Close, Martins Heron, Bracknell, Berkshire, England, because British addresses just don't know when to stop.
The two story, three bedroom house features an attached garage and is selling for 475,000 pounds, which works out to a little under $620,000. Yikes! That seems a bit steep for a house that's slightly over a thousand square feet. I'm sure the fact it was featured in the films has nothing to do with the inflated price.
The house was used only for exteriors during filming, as the interiors were all shot on a sound stage.
The listing features a few shots of the actual interior, and it looks like the realtor pushed their wide angle lens to its limit in a flailing attempt to make the place look bigger than it really is. How can I tell they used a wide angle lens? Because most wall clocks are circular, not stretched out ovals, that's why.
The home also features a garden, or "back yard" to us non-Brits. The wide angle lens got a workout here too, unless the house really is shaped like some sort of extreme trapezoid.
I can only imagine the living hell the new owner of this house will have to endure, as carloads of fans pound on the door day and night, demanding to see Harry or get a look at the cupboard under the stairs. Hopefully the owner has a good wand and knows the Crutiatus Curse. Crucio!
