FAQs

What do the proposals for the British Library extension include?
The extension to the British Library comprises of new public spaces for exhibitions, events, learning and business support, as well as green spaces outside and a community garden. The scheme also provides commercial space and accommodates Crossrail 2 infrastructure, which will be integrated into the site.
What are the timescales for the delivery of this scheme?
The project has a long delivery timetable, in part because of the need to provide underground infrastructure for Crossrail 2 while keeping the British Library operational at all times. Construction starts in 2026 and the new Library spaces are expected to open in 2032.
How many jobs will be created by the scheme? How many of these will be ‘local’?
The project will create a range of employment opportunities during both the construction phase and once the extension is operational. As part of the Section 106 agreement, SMBL will provide apprenticeships and work experience opportunities, as well as a substantial construction workforce. SMBL will work with the Camden Construction Skills Centre to ensure up to 20% of construction roles are filled by local people, alongside the delivery of 75 apprenticeships.
What will be the impact of disruption on local people?

As with any construction project, there may be unavoidable periods of noise and disruption once work starts. The existing British Library building will, however, remain open throughout and as these works will take place behind the current site, Library services are not expected to be affected.

Look out for news alerts about particularly disruptive works. If you have any questions or concerns about work on site, please contact David Demolder at David.Demolder@macegroup.com.

What has been agreed and how will the works be carried out?

A copy of the draft Construction Management Plan (CMP) can be found here. A Construction Working Group meets regularly to ensure the works are managed in accordance with the CMP plan.

When is work starting on site?

Site clearance work commenced in January 2026. The Main works will start in Summer 2026.

How long will it be before we see a structure starting to appear?

Most of our works will be in the ground until 2027. It is likely to be several years before the structure of the new development starts to appear above ground.

What are you doing to mitigate the impact of dust and noise while work takes place?

We will use dust and noise suppression techniques such as damping down, acoustic screens and ensuring machinery is switched off when not in use.

Will the roads around the site continue to operate as normal?

Yes they will. Our main entrance and exit will be off Midland Road. 

Which roads will be used for site access?

Midland Road will be the main access point for the site. Ossulston Street will only be used as a secondary access and does not form part of our normal access arrangements.

Will local services such as water, gas and electricity continue to operate as normal?

Yes they will continue to operate as usual.

What measures are in place to communicate what is happening on site to local people?

Mace will distribute regular newsletters, works notices and post information on his website as well as on notice boards around the site.  In addition, a community engagement manager, Salima Abdallah, has been appointed who will respond to enquiries, keep people informed and coordinate with other local engagement managers such as The British Library and Francis Crick Institute. You can send any comments or questions to Salima@somerstown.org.uk

How will you work with key neighbours such as the Francis Crick Institute (FCI) during the development?

We are working closely with neighbours in surrounding buildings to plan our work schedule and will liaise with them regularly to avoid inconvenience to them and other neighbours as the works progress. The regular A Construction Working Group has been set up and includes representation from the FCI as well as local residents, LB Camden, the British Library and ward councillors.

What measures are you taking to ensure that local businesses benefit from the works?

We’re seeking to use businesses and suppliers local to Camden. We will be hosting ‘Meet the Buyer’ events to explain the services we are looking for and help businesses to be better prepared for working with us. We will also work with local businesses to help them make the best of the opportunities provided by the site and our workforce, such as providing catering and other relevant support services.

Will the temporary accommodation for those working on site overlook my home?

Until summer 2027, our temporary accommodation will be close to Midland Road. Accommodation will then be relocated to the Ossulston Street side of the site. While this will provide some screening from works on site for the immediately neighbouring properties, we will also ensure that local residents are not overlooked or disturbed by lighting or CCTV.

What other benefits does the development offer the local community?

The British Library extension will offer a wide range of benefits during its development including:

    • Local job and training opportunities with the project team and supply chain partners
    • Employment training and work placements for local residents
    • Engagement with local schools, colleges and universities to offer STEM activities and work experience placements for local students
    • Supporting local charities and community groups with fundraising, in-kind support and pro-bono work
    • A £23 million contribution to the delivery of new affordable homes in Somers Town
