Award RIBA London Award 2025

The award winner tells us: "The Royal College of Obstetricians and Gynaecologists (RCOG) has relocated to a new building designed by Bennetts Associates at 10–18 Union Street in Southwark.
This new democratic and inclusive headquarters for the historic medical institution is part of a wider programme of modernisation by the College who had previously occupied leasehold premises in Regent’s Park. The move has allowed them to occupy a city-centre location and own their own building for the first time, representing a significant cultural shift.
The building is an exemplar in adaptive reuse and lean design, knitting together two existing buildings, a converted 19th-century warehouse and a 1980s office building by creating a new central atrium with new workspaces for College staff and partner organisations, conferencing facilities, and a public café."
The jury says: "The existing buildings – a converted 19th-century warehouse and a 1980s office block – were separated by a hard, unloved external space, and consent had been granted for their demolition. This project is a clever and affordable solution that knits the buildings together to create new workplaces and conference facilities for the RCOG and their partner organisations. The design team and client have been careful with where they chose to spend their available budget, concentrating on adaptive reuse rather than remodelling the entire building."
