The eight-unit development will see a number of steel-framed units including an M&S Foodhall, six-screen Reel Cinema, restaurants and other new businesses come to the growing market town.
John Wilson of Eric Wright Construction, said: “As a local contractor we are extremely proud to be delivering this scheme with Chorley Council and look forward to getting the main build under way.
“It offers a modern two-storey extension to the existing shopping centre which will become a major feature within the town.
“The scheme complements a lot of other work taking place to improve the appearance of Chorley town centre, such as the Primrose Gardens retirement village we are also constructing on Fleet Street.
“Chorley Council is working hard to provide a long-term future for the town and we are pleased to be a part of it.”
