Key planning application documents will also be available to view from Monday 4 April at the British Library, located on the Upper Ground Floor near to the existing model.

SMBL were selected by the British Library as their development partner to bring forward the plans for the site. SMBL have spent several years working with the British Library and TfL getting to know the Somers Town area and community leaders, resident groups, schools, and other organisations.

We want to hear your views to make sure this project delivers for everyone in the local community. Find out more on how you can be involved here.

The British Library is home to one of the most important collections of books, manuscripts, newspapers, maps and sound recordings in the world.

Now, a once-in-a-generation transformation is being planned to extend the British Library’s site in London to make it the most open, creative and innovative institution of its kind anywhere in the world, which is an important part of the British Library’s “Living Knowledge” vision.

The project to take this vision forward is a partnership between the British Library and SMBL Developments (a joint venture between Stanhope Plc and Mitsui Fudosan UK Ltd).

Visualisation of the British Library Extension.

The British Library extension

The British Library extension will provide a wide range of benefits for the local community. It will completely open up the British Library to the north east and west. New publicly accessible spaces, squares and routes will be created to connect the Library to Somers Town and St Pancras.

The British Library extension would also become a meeting place where everyone can visit and enjoy the Library and the new opportunities created, and will provide a new headquarters for The Alan Turing institute, the UK national centre for data science and artificial intelligence.

There are three main aims to this project:

1. Growing the library

Creating more capacity for Camden residents, visitors, schoolchildren, students, researchers, workers and businesses as well as new spaces for exhibition galleries, an events space, and additional facilities for learning and business.

Improving the public realm and connections to Somers Town, through opening up the site and providing new entrances to the British Library Extension at the north which will be accessible from both Midland Road and Ossulston Street, closer to Somers Town, to improve access for the local community.

2. Creating the heart of the Knowledge Quarter

This site is located at the heart of the Knowledge Quarter, one of the greatest concentrations of knowledge-based cultural and scientific businesses anywhere in the world.

A significant part of the extension will comprise commercial space to be leased to those who want to work and collaborate with businesses and communities in the Knowledge Quarter, joining other research-based institutions near the Library such as the Francis Crick Institute and The Alan Turing Institute.

3. Unlocking London’s largest transport hub

The site will support the future creation of a new underground station for Crossrail 2 by connecting Euston and St Pancras. This will mean that the area is the most important transport interchange in the UK.

The Library’s new spaces and the Station Works infrastructure for Crossrail 2 beneath the site would be funded by new commercial space (c 600,000 sq ft). This will also create more job opportunities within the Knowledge Quarter.
