The set of Coronation Street is to be rebuilt at a new larger location in 2013.
The new street, complete with the soap's famous houses and cobbles, will be constructed to a larger scale to cater for the demands of high definition TV.
The site covers 7.7 acres. Planning permission is needed.
The BBC reports a larger set will also give the series an option of expanding with the building of new parts of Weatherfield.
The current Coronation Street set at the Granada complex in central Manchester, has been used since 1982. Its terraced houses are slightly smaller than real houses.
ITV said the new outdoor set would be built "to greater scale than before".
Coronation Street was based on a terraced road in Salford when it was devised by creator Tony Warren in 1960. The show has just celebrated its 50th anniversary.
