A contemporary house inserted into the twelfth-century ruins of Astley Castle in Warwickshire by Witherford Watson Mann has won the RIBA Stirling Prize 2013 for the greatest contribution to British architecture in the last year.
This is the first time London studio Witherford Watson Mann has been nominated for the prize, which is awarded annually by the RIBA to a building designed by a UK-registered architect. It is the first house and the first restoration project to win the award in its 18-year history. via dezeen
