Grimshaw create new stations for major tube line development

The Mayor of London officially opened London Underground’s Northern Line Extension on 20 September, with two new tube stations designed by Tenderstream members Grimshaw welcoming passengers for the first time. The two step-free Zone 1 stations at Battersea Park and Nine Elms are expected to dramatically improve the connectivity of these south London neighbourhoods, while supporting the capital's recovery from the pandemic. In addition to the tube stations, Grimshaw also designed a residential oversite development at Nine Elms, two new ventilation shaft head houses in Kennington and new cross passages at Kennington Station.

The Nine Elms station has a visible presence on Wandsworth Road, serving developments including the US Embassy and the re-developed New Covent Garden Market, as well as existing communities. The station has been designed so that 479 new much-needed rental homes, 40 per cent of which will be affordable, can be delivered above and around it. The station at Battersea, which sits in the shadow of Gilbert Scott's Power Station, includes a gold-painted geometric roof with a giant skylight. A major new permanent artwork by London-based Brazilian artist Alexandre da Cunha stretches to a total of over 150m in length inside the ticket hall. 

Sadiq Khan, Mayor of London, stated: “After an incredible effort from the huge number of people who worked on this project. The two new stations at Nine Elms and Battersea Power Station are the first new stations on the Northern line for 80 years. They will hugely improve connectivity between these two areas and the rest of London and play a major part in the capital’s recovery from the pandemic by supporting thousands of new jobs, homes and businesses.”
