Major plans to expand Boundary Mill in Colne – founded by the Bannister family of Coniston Cold – have been unveiled.
Land near the mill complex, at the end of the M65, has been earmarked for a new garden centre and farm shop by the company, headed by Richard Bannister.
It could create up to 300 jobs for East Lancashire.
Proposals submitted to Pendle Council show that a new roundabout would be created on Whitewalls Drive, to cope with the traffic demands of the new store.
Under the scheme, drawn up by Manchester-based Nexus Planning, the garden centre would face away from the M65, with a 452-space car park positioned in front.
Director Peter Tooher said: “It is intended that the development will enhance the flagship retail role of the existing Boundary Mill Stores, providing in the order of 300 new, full and part-time jobs on an important gateway site.”
