Sainsbury’s has submitted a planning application to Welwyn and Hatfield Borough Council to build a larger, store at its site in central Welwyn Garden City, Hertfordshire.
The supermarket chain proposes to replace its present store with a 37,700 sq ft outlet.
The new store will feature a 16,500 sq ft mezzanine level which will sell non-food ranges and host a café.
Sainsbury is also looking to add two-level underground parking facilities with 420 spaces, with road and landscaping improvements.
The public exhibition it held on 4 and 5 April showed 87.5% support for the store redevelopment.
Robert Oxley, Development Executive for Sainsbury’s, said: 'With our current store clearly in need of improvement, Sainsbury’s was encouraged by the strength of support for our plans. We believe the new Sainsbury’s store will provide a huge commercial boost to the town centre, helping keep more trade within Welwyn Garden City.'
