Work on the feasibility study will be carried out over the next eight months, with the four new stations – Burgess Park, Old Kent Road, New Cross Gate, Lewisham.

The project is expected to cost between £5bn and £8bn and could be operational by 2040 according to TfL, subject to planning and funding approval.

WW+P, which is lead architect for the project, will focus on the design aspects with AECOM responsible for all engineering matters, including civil, structural, mechanical and geotechnical engineering, as well as stakeholder engagement and consent.

Steve Bell, Regional Director – Europe at WW+P said: “We’re pleased that our work could see the progression of one of the most significant next programmes of regeneration in the region centred around transport-oriented development.”

Unlike most Underground lines, the Bakerloo line currently terminates in Zone 1 in central London, with its final stop at Elephant & Castle. This has been the case since the line opened in 1906, with various proposed extensions over the past century.

The current proposal will see the line run to Lewisham in Southeast London, improving accessibility and reducing journey times to the city centre.
