Russells Construction has completed a 100,000 sq ft cold store warehouse in Heywood, Greater Manchester, for Yearsley Logistics.
The unit comprises the first two phases of a three-part expansion of the firm's northern distribution centre, adding 28,000 pallet spaces to the existing capacity of 40,000 pallets.
There will ultimately be a total of 450,000 sq ft and 80,000 pallet spaces at the Heywood site.
Harry Yearsley, managing director of the £156m turnover firm, said: "This expansion is in direct response to demand from new customers for whom the North West is an ideal location.
"Our existing Heywood store was running near to capacity and this expansion will amount to a £20m investment in facilities for our customers and secure jobs for our employees.
"It is part of our long term plan to consolidate stock in strategically located stores, helping us to increase efficiency, reduce carbon output and better meet the storage needs of manufacturing customers and the delivery requirements of retail and food service customers across the country."
Yearsley Group has a network of 13 cold stores across the country, with Heywood serving as the centre of its UK operation.
The super-insulated unit – which will operate at minus 25 degrees celsius – is one the most energy efficient example of its type in the country.
It is built to BREEAM Very Good standard and boasts a state-of-the-art racking system.
Russells Construction, Trafford, completed the build within a tight nine-month construction programme to help Yearsleys meet its contract obligations.
