Tyneside-based bank Northern Rock has unveiled plans to redevelop its base in the city.
The existing block was built in 1965
The company has lodged an application to redevelop its 1965 tower block at the Regent Centre in Gosforth which could create 1,000 new jobs.
This latest £30m phase of an expansion scheme, which has been carried out in recent years at the head office site, is due to be completed in spring 2005.
The company says the Regent Centre building needs to be updated.
It says the building has served the company well but is now less efficient than other modern forms of construction.
It says it has also been involved in developing a sustainable travel plan for the Regent Centre area.
