Old Swan House: grade I listed building By Sir Norman Shaw
Price: £32 million ($57 million)
Location: 17 Chelsea Embankment, London
Old Swan House is one of the largest houses in Chelsea. It was designed by the renowned Victorian architect Norman Shaw in 1875, and it continues to have commanding views over the River Thames towards Battersea Park from its second floor ballroom. A Grade II-listed house--which means it must be preserved by British law--this 19,000-square-foot home still has its brick exterior intact, as well as five principal bedrooms and 11 staff bedrooms, a dining room that seats 20, private terraces, a swimming pool complex with sauna and showers, a passenger lift, air conditioning, state-of-the-art security and hi-fi systems. Do not forget the cinema and parking for five cars.
