Plans for the development of the "first new West End theatre in more than a decade" have been approved by Westminster City Council as part of London's Crossrail scheme.

The new venue will occupy the capital's former Astoria site as part of the transformation of the Tottenham Court Road area, with retail, residential and office space also proposed.

Crossrail submitted its plans in conjunction with Derwent London, which cover two surface schemes above each ticket hall of the integrated Crossrail and London Underground station.

Derwent London has already entered into an agreement with Nimax for the operation of the new 350-seat theatre, which forms part of plans for two of four development sites designed by architects AHMM.

HawkinsBrown have also worked on designs for part of the Tottenham Court Road vision, which is expected to cost around £1bn and also covers the eastern end of Oxford Street.

Crossrail land and property director Ian Lindsay said: "The £1bn redevelopment of Tottenham Court Road station provides a once in a generation opportunity to revitalise the eastern end of Oxford Street.

"The plans including high-quality offices and shops will enhance the Oxford Street and Charing Cross Road area as a thriving cultural and retail destination."
