Plans for a supermarket, petrol station, a six screen cinema, a hotel, office blocks and a healthcare facility to be built in Derry have been lodged with the planning service.
It's claimed the development will create thousands of jobs.
Applicant GSB Guernsey Trading Limited, which is part of the Orana Group, proposes to site the new developments on vacant land adjacent to Lisneal College.
The proposals for the 56 acre site involve two applications - one for a Sainsburys superstore and a petrol station, with the potential to create 500 full and part-time jobs.
And a second development for a cinema, hotel, office blocks, a healthcare facility and other retail outlets, which could create 800 full and part-time jobs.
The Orana Group also revealed that it has similar plans for both Bridgend and Strabane.
