The Co-operative Food store in Werrington is being transformed with a £400,000 investment.
It is hoped the Loxley Centre store will become a hub for the community as well as a place to shop.
The new-look store will open on Saturday.
The store is being extended by 650 square feet to provide a sales area of around 2,200 sq ft. The in-store bakery is being increased.
Debbie Lucas, team manager at the store, said: “I’m excited about welcoming shoppers into the new store. The transformation will be amazing, and I’m sure our customers will enjoy shopping in the new environment, The store is currently closed for the refurbishment work.”
