Landmark Project to Enhance Cultural and Commercial Spaces Near St Pancras
A £1.1 billion expansion of the British Library has been confirmed following financial backing from Japanese developer Mitsui Fudosan, marking a significant international investment in the capital.
Approved by Camden Council last July, the project had been awaiting confirmation from developers before moving forward. The extension will add approximately 100,000 square feet of new public space dedicated to cultural, educational, and research facilities, including expanded galleries and business support areas. Additionally, 600,000 square feet of commercial space will be developed, targeting businesses in the life sciences sector near the Francis Crick Institute and the Alan Turing Institute in London’s Knowledge Quarter.
Designed by architects RSHP and engineers Arup, the development will introduce new public entrances, pedestrian-friendly routes, and open-access areas connecting the library with the surrounding neighbourhoods. Construction is expected to begin in 2026, with completion set for 2032.
Under the agreement, the British Library will grant a long-term lease of the extension site to SMBL, a Mitsui Fudosan-owned development partner, with Stanhope overseeing project management.
Commitment to Culture and Innovation
Takeshi Iwama, CEO of Mitsui Fudosan UK, expressed enthusiasm about the project, calling it a milestone investment that blends cultural expansion with scientific innovation. “We are proud to contribute to the growth of one of the UK’s most significant institutions while ensuring our investment benefits both local communities and the broader economy,” he stated.
Rebecca Lawrence, Chief Executive of the British Library, highlighted the initiative as a step towards transforming the library into a hub for knowledge and innovation. “This extension will not only enhance public access but will also create cutting-edge spaces for research and collaboration,” she said.
Local Benefits and Regeneration
As part of the agreement with Camden Council, the project will contribute £23 million towards affordable housing in Somers Town, funding 35 new homes. It will also provide 10,000 square feet of affordable workspaces, with a portion reserved for local entrepreneurs. Additional improvements include new cycle docking stations, pedestrian-friendly infrastructure, and a community garden on Ossulston Street, co-designed with local residents.
Economic and Urban Growth
Deputy Mayor for Business and Growth, Howard Dawber, welcomed the investment, calling it a transformative addition to London’s Knowledge Quarter. “This project cements London’s status as a global leader in research and culture while generating jobs and supporting regeneration efforts,” he said.
With construction set to commence soon, the British Library’s expansion is expected to serve as a landmark development, enhancing both public and commercial opportunities in central London.
