For over 30 years, Purcell has supported the National Gallery through a series of sensitive and ambitious projects. This longstanding partnership has helped the world-renowned institution to adapt, grow and welcome millions of visitors while safeguarding its rich architectural legacy. Purcell has led a range of initiatives, from conservation and design projects to major gallery refurbishments, to the most recent NG200 capital programme, including the reimagining of the Sainsbury Wing in collaboration with Selldorf Architects. As part of the gallery’s bicentennial celebrations, a series of capital works were commissioned by the gallery. Working along Selldorf Architects – who led the design vision – as executive architect and heritage consultant, we have transformed the Grade I-listed Sainsbury Wing, reimagining it as an inclusive gateway to the UK’s national art collection. Purcell developed a conservation management plan that balances the building’s postmodern character with 21st-century needs, respecting Denise Scott Brown and Robert Venturi’s original design ethos. Instead of a single bold gesture, the design introduced a series of targeted improvements: a new public forecourt, a reimagined entrance, and upgraded amenities — all enhancing the experience without compromising the original architecture.
