Located in Chelsea, an affluent area of central London, is a home with a unique feature. The four bedroom, four bathroom home has a top floor family area with a retractable glass roof. The home is available for sale and is being listed by Carter Jonas for a cool 3.75 million pounds (approx. $6 million USD).

The first two pictures below show the original design from the architect while the final two pictures (#9, #10) show how the owners have actually decorated the space to be more of a family/living room space.
