British Library plots mammoth commercial office extension

The British Library has unveiled plans for an 800,000 sq ft extension to its King’s Cross home, most of which will be commercial office space. The proposals, drawn up by architect Rogers Stirk Harbour & Partners, will involve about 770,000 sq ft of commercial space. A joint venture between Stanhope and Mitsui Fudosan UK is bringing the project forward. It will also include new library facilities as well as underground enabling works at part of the site for a proposed Crossrail 2 station. The British Library is expected to submit the proposals for planning in late spring. If it gets the nod, construction is due to start in late 2023. The scheme will be built on a largely undeveloped 2.8-acre plot at the back of the existing building, creating a space for a new Knowledge Quarter and home for the Alan Turing Institute. It will also involve demolishing buildings on the north side of the library, including the British Library Centre for Conservation. The new building will include three basement levels connecting into the existing building, a large foyer and offices above.
