The Royal Institute of British Architects (RIBA) has announced the 20 winners of the RIBA National Awards 2025, which have been presented since 1966 to celebrate the best architecture in the UK. The awards highlight design excellence, innovation, and social value, offering insight into the country’s evolving architectural landscape.
Winning projects span a wide range of types and locations, from major civic buildings and scientific facilities to housing, conservation, and community-led schemes.
These projects now form the longlist for the RIBA Stirling Prize, the UK’s most prestigious architecture award, with the shortlist due on 4 September 2025. Since their inception in 1966, the RIBA Awards have recognised projects of all scales that set the standard for excellence in UK architecture. Photo of 8 Bleeding Heart Yard by Tim Soar Gallery.
