Witherford Watson Mann Architects was established in 2002 by Co-Directors Stephen Witherford, Christopher Watson, and William Mann. Known for projects that reinforce and complement the characteristics of existing spaces with focused and crafted additions, the practice's best-known building, Astley Castle for the Landmark Trust, won the 2013 RIBA Stirling Prize for its distinctive entwining of past and present. The new theatre for Nevill Holt Opera, built within the courtyard of an historic stable block, both won the regional Stirling Prize and was shortlisted for the national 2019 Stirling Prize. Both projects won the ‘Stirling Prize People's Vote’.
