This very striking house is called Villet's House.  It is in Cricklade Street in the Old Town area of Swindon.  It is elaborately decorated and once described by Sir John Betjemen as "The finest house in Swindon".  But the house has secrets, including underground tunnels and a 10-inch thick steel door.  For photographs of these tunnels and some of the inside of the house during its renovations, visit the  BBC Website.

It is a Grade II* listed building - for details about the listing see the  Historic England  website.
