Groundbreaking ceremony

British Offsite recently held a ceremony at Horizon 120 business park.

Upon completion


The British Offsite factory and facility at Horizon 120 business park will help the local economy by employing up to 80 people.

The mega-factory will manufacture and distribute building components that British Offsite sell to the new homes industry.

The company’s UniPanel system range includes light gauge panels, walls, roofs and floors alongside internal fitout modules, under the BOS Fitout brand, including bathroom components, kitchen and bedroom products.

Swedish partner Randek AB will deliver the factory’s £6 million production line.

These products will then be sold on to housebuilders, builders and contractors in the construction sector, with clients including parent company Weston Group.

More about British Offsite
