I'm not sure exactly when this episode aired, but the windmill shaped house at Wraysbury, Surrey, was featured in the
current series of
60 Minute Makeover.
The
series as a whole has reached episode 50, and the Wraysbury one
was number 35, so it could have been some time ago.
The Wraysbury windmill was in fact always built as a house, for around £45,000 in 1996. Its design is based on the smock
mill at Lacey Green. There are some plans to install sails so that the mill can generate electricity.
