An investigation has been launched after a fire broke out on Aycliffe Business Park.
The timber fire caused extensive damages to the warehouse at Appletree Joinery, on Linde Way, on Sunday.
Residents were urged to keep all doors and windows shut at one point as a huge plume of smoke hung over.
Rob Cherrie, group manager at County Durham and Darlington Fire and Rescue Service said: “We were called to a fire in the Linde Way area of Newton Aycliffe at 8.40am.
“A worker noticed a fire and when we arrived the fire was well established in one of the areas. We knocked it back, but there is another huge warehouse right next to it, full of wood and stuff and the fire got into there.
“We got from two fire engines to six appliances very quickly, as well as an aerial ladder platform. At the height there were ten appliances on the scene.
“We saved all the machinery in the workshop, which is great.”
A joint investigation between the fire brigade and Durham Police is being carried out to establish the cause of the fire.
