We're going west for this one... out to Shepperton, I guess the fringes of what anybody could reasonably call London, but the journey's worth it, because this time we're looking at a three bedroom house on a Thames island, accessible only by boat. It comes with grounds, a swimming pool, a sauna and (strangely, perhaps) a garage. It's on Pharaoh's Island - apparently so named because it was given to Lord Nelson after his victory at the Battle of the Nile. It's listed at £1.1 million. More here.
