National Express wants to relocate coach services to a temporary site while it begins rebuilding the infamous Digbeth coach station.
A planning application will be submitted today to Birmingham City Council (BCC) for the move to Oxford Street, directly opposite the existing site.
The move will maintain coach operations during the redevelopment of the much criticised coach station - for which noted architect Ken Shuttle-worth has been working on designs since being appointed last year.
If planning permission is granted, the site bounded by Oxford Street, Coventry Street and Meriden Street - previously part of the Volkswagen garage and showroom room - will be known as Birmingham coach station.
A short-term lease would be taken on site with the intention of moving back on to the redeveloped main site by mid-2008.
Marc Sangster, director of strategy at National Express, said: "The planning application marks the start of an exciting time for National Express in Birmingham.
"We are delighted to have found a site which has a great location and will provide excellent temporary facilities, better than that currently offered at the existing site.
"The move to a temporary site will help to confirm our intentions to build a new world class coach station that the people of Birmingham can be proud of."
National Express will also be holding an open public exhibition, at a venue to be confirmed, on Friday January 20 (10am-8pm) and Saturday January 21 (9am-4am) where people can look at the proposals.
Architect Shuttleworth, whose brief is to design a new "world class" station, is best known for the London 'Gherkin'.
The redevelopment is intended to assist with the regeneration of the Irish Quarter.
Mr Sangster added: "We will submit an outline planning application for Digbeth Coach Station to BCC in early 2006.
"It is our intention that the redevelopment will be complete and re-opened by mid-2008."
