The British Museum has shortlisted five architect-led teams in an international competition to transform its Western Range Galleries—one of the most ambitious redevelopment projects in the institution’s history.
Covering more than 7,500 square metres of gallery space, the project will reshape the presentation of collections from Ancient Egypt, Greece and Rome while upgrading the infrastructure needed to preserve and manage them. It will also support the museum’s wider ambitions around accessibility, sustainability and long-term estate resilience.
The Western Range is a vital part of the British Museum’s historic Bloomsbury estate. It accounts for almost a third of the museum’s gallery space and includes significant back-of-house, operational and collection-support areas.
In total, the range extends across approximately 15,650 square metres. Some of its oldest sections date from the 1850s and form part of the neoclassical museum complex designed by architect Sir Robert Smirke. Later additions include Galleries 10 and 22, creating an estate that reflects several different periods of architectural and institutional development.
The age, scale and complexity of these buildings make the redevelopment especially challenging. The successful design team will need to protect the character of the historic estate while introducing the environmental controls, technology and visitor facilities required by a modern international museum.
The Western Range project is not simply a gallery refurbishment. It requires a comprehensive rethinking of how historic spaces can support collections, visitors and museum operations for generations to come.
The selected team will need to balance several priorities, including:
Achieving these goals within a highly sensitive historic environment will demand close collaboration between architects, engineers, conservation specialists, curators and facilities professionals.
Sustainability will be central to the project.
Historic museum buildings are particularly demanding to operate because valuable collections require carefully controlled temperature, humidity and lighting conditions. At the same time, cultural institutions are under growing pressure to reduce energy consumption and carbon emissions.
The Western Range redevelopment therefore presents an opportunity to improve building performance without compromising conservation standards or architectural integrity.
Potential interventions may include more efficient environmental systems, improved building fabric and carefully integrated low-carbon technologies. The challenge will be to introduce these improvements sensitively within spaces that were never designed for modern mechanical and electrical infrastructure.
The five shortlisted teams progressed to the second stage of the international design competition, during which they were invited to develop detailed proposals for the Western Range.
The designs were due to be presented in the British Museum’s iconic Round Reading Room, giving the public an opportunity to explore the competing visions for the future of this important part of the estate.
The judging panel was chaired by George Osborne, Chair of the British Museum’s trustees, and included leading figures from architecture, design, museums and cultural heritage. Panel members included Yvonne Farrell, Meneesha Kellay, Mahrukh Tarapor and Sarah Younger.
The competition was expected to conclude with the selection of a winning team in early 2025.
The transformation of the Western Range is set to become one of the most significant architectural and estates projects undertaken by the British Museum.
Its success will depend on more than striking design. The finished spaces must protect priceless collections, support complex museum operations and provide an exceptional experience for millions of visitors.
The project also offers an important example of how major cultural institutions can adapt historic buildings for modern use. By combining conservation, sustainability and innovation, the British Museum has an opportunity to create galleries that honour the estate’s architectural heritage while meeting the expectations of future generations.
The winning proposal will shape not only the physical future of the Western Range, but also the museum’s continuing evolution as a modern, accessible and environmentally responsible cultural institution.
