The British Museum's major transformation is progressing, with contracts tendered and designs approved for a project tipped as the "biggest cultural renovation" of its kind in the world.
Last month the museum put out to tender over £1 million in security, IT and logistics contracts attached to the third phase of its redevelopment masterplan – a drop in the ocean for a project set to deliver a "complete reimagining" of a third of the gallery's floor space.
Western Range revamp
Housing the site's "greatest objects from ancient Greece, ancient Egypt, Rome, Assyria and the Middle East", the revamp of the Western Range is poised to install state-of-the-art storage facilities and introduce "engaging" modern architecture to the buildings.
First opened to the public in 1759, the current building was designed by Sir Robert Smirke in 1823 and completed in 1852. The building's colonnade is held up by 43 columns inspired by ancient Ionian ruins in Athens and Priene, and is probably Britain's most famous example of the Greek Revival style.
Today, the Grade I listed museum attracts six million visitors a year and is home to artefacts like the Rosetta Stone and the Parthenon sculptures.
Design and approvals
In February 2025, designs for the Western Range's renovation from renowned Lebanese architect Lina Ghotmeh won out among stiff international competition. Official design work began in June 2025, and is expected to be finished later this year.
In March Camden Council approved controversial plans for new Welcome Pavilions, including security admission buildings, which are set to open in 2027.
Funding and support
The financing for the entire masterplan has not yet been sewn up, but comes from a combination of government and charity grants, sponsorship deals and private fundraising.
Donors like the Maughan Family have established a dedicated fund for the Western Range alone. The UK government has committed direct capital support to the new Energy Centre, while providing at least £80 million in revenue and capital for the museum's general budget in 2025/26.
In 2025 the museum held its inaugural Pink Ball, where the museum raised a gross total of £2.5 million. Roughly £1.6 million was generated from 800 privately sold, invite-only tickets. Guests included Sir Mick Jagger, the Mayor of London, Maya Jama and Dame Tracey Emin. The remaining funds came from a silent auction and private auction.
A further £10.3 million pledge from the grant-giving charity Garfield Weston Foundation was announced at the event, and will be used towards the new Welcome Pavilions at the North and South Entrances. Meanwhile, construction contracts for the Energy Centre Programme, beginning in 2024, were valued at £33 million.
The museum has invited criticism from climate groups after it accepted £50 million from BP towards the development. At last year's Pink Ball, Chair of Trustees George Osborne was notably confronted by a worker over the sponsorship, which has bestowed the oil company's name on a lecture theatre.
However, according to the museum's annual report and accounts, the funding for the Western Range programme is yet to be fully secured. As of March 31, 2026, the designated masterplan fund stands at £16 million but the delivery of phase three is "dependent on the ability of the museum to raise sufficient funds".
The museum says it is progressing with its fundraising campaign to support the concept design and development stages, though these were initially due to be unveiled by mid-2026. A second fundraising ball will take place on October 17, 2026, with tickets this time priced at £3,500 per head.
Planned projects at the museum
Project: A new facility for the storage, study and lending of British Museum objects, in partnership with the University of Reading. Funded predominantly by government investment following the sale of the Grade II listed Blythe House, which was used as an archive and storage facility for the British Museum and others. Location: Thames Valley Science Park, Reading. Cost: £64 million. Status: Complete (opened 2024).
Project: Tipped to reduce the museum's carbon footprint, the ECP is set to modernise the museum's service infrastructure including its primary power supply and heating system. The museum expects this will deliver an annual net saving of 1,700 tonnes of CO2. Location: British Museum Bloomsbury Campus. Cost: £33 million+ (fully funded by UK government). Status: Currently scheduled for completion by 2029.
Project: Rebuilding and restoring 10 separate buildings amounting to a third of gallery floor space, to "make them suitable for the 21st century". The redesign will prioritise visitor experience as well as creating "beautiful spaces", plus new collection stores and research facilities. Location: British Museum, Bloomsbury Campus. Cost: TBC. Status: TBC.
Project: Reimagining the two public entrances on the South Forecourt at Great Russell Street and the north entrance on Montague Place, replacing the existing security tents and barriers. Location: British Museum, Bloomsbury Campus. Cost: TBC. The project has received at least £10.3 million in charitable donations. Status: Approved by Camden's planning committee in March 2026, the south pavilion is scheduled to open in 2027.
