Transport for London confirmed on 15 September 2026 that Costain will be appointed to design and build a multi‑phase redevelopment of South Kensington Underground station. The programme aims to introduce step‑free access to the Circle, District and Piccadilly line platforms, improve the ticket hall and museum subway, and construct a dedicated eastbound platform for Circle and District line services.
Why South Kensington station matters

Transport for London plans to submit an application for the new stations at Beckton Riverside and Thamesmead early next year.
South Kensington station opened on 24 December 1868, making it one of the network’s earliest stations. Designed under the direction of engineer Sir John Fowler, it originally linked the Metropolitan Railway with the Metropolitan District Railway. The station’s historic significance grew as the area developed into a museum district, supported by the pedestrian subway opened on 4 May 1885 beneath Exhibition Road.
The subway, 433 metres long, was built to shelter museum visitors from street traffic and was initially subject to a toll. It became free to the public in 1908 and retains much of its cream and yellow‑brown glazed brickwork. Historic England granted the station Grade II listed status in August 2004, recognising the original pale‑yellow brick arches around the Circle and District platforms and an Edwardian shopping arcade designed by architect George Sherrin.
Planned improvements and heritage protection

An unattended item prompted a temporary closure and evacuation of the busy London transport hub.
TfL’s proposal, as outlined in the September 2026 announcement, includes installing lifts and ramps to achieve step‑free access across all three lines, refurbishing the historic arcade, and delivering a new four‑storey building that will house commercial space and 50 residential units. The plan also calls for upgrades to the museum subway, ensuring it remains functional for the high visitor numbers that the nearby Victoria and Albert, Natural History and Science museums attract.
TfL stressed that the redevelopment will protect the station’s listed features. The historic brick arches, the arcade’s glazed roof and decorative ironwork will be retained and restored where necessary. The new construction will be set back from the listed elements to minimise visual impact.
Next steps and how the public can respond
Awarding the contract to Costain marks the transition from planning to detailed design. TfL will now seek planning permission from the London Borough of Kensington and Chelsea and will launch a public consultation on the detailed designs later in 2026. Residents and museum users will be invited to comment on access routes, the proposed homes and the preservation of heritage features.
Following the consultation, TfL expects to submit a planning application in early 2027. If approved, construction could begin in 2028, with the aim of completing the works within a five‑year window. TfL will provide regular updates through its website and local community meetings.
