Barnet Council is looking for a design and build team for the proposed £215 million train station at Brent Cross West.
The winner of the £40 million contract will oversee the detailed design and delivery of the new Midland Main Line station which already has outline planning permission.
Brent Cross West Station, planned to complete in 2022, will host Thameslink services connecting the area to London Kings Cross St Pancras in 12 minutes.
The station is part of the wider regeneration of Brent Cross Cricklewood, including 7,500 new homes and the £1.4 billion redevelopment of Brent Cross shopping centre.
Brent Cross West Station will sit between Cricklewood and Hendon stations on the Midland Mainline out of London St Pancras. The new regional interchange station will feature four platforms, an open concourse and a pedestrian overbridge; and is expected to host two million passenger journeys in its first year. The deadline for applications is midday, March 4.
