This spectacular two-bedroom apartment is configured across five storeys, in the tower of St Thomas's Church, in London Bridge. Originally built in 1703 by Thomas Cartwright, an architect and master mason of Christopher Wren, the church was used as a chapter house for Southwark Cathedral and in part, as an operating theatre for St Thomas's Hospital. The apartment has just had a roof terrace added to the top floor, creating astonishing views of the city skyline.
