The 2013 RIBA Stirling Prize has been won by Witherford Watson Mann for Astley Castle (Nuneaton, Warwickshire). The winner was just announced at a ceremony at London's Central Saint Martins, a building designed by last year's winner Stanton Williams. Astley Castle was also voted as BBC readers' favourite earlier this week. Jury-member Stephen Hodder stated that "engaging with the building was such a surprise for [the jury]," and described it as an "unassuming" building with great "rigour."
