The company is starting with the construction of a new £4.5m factory on land adjacent to its existing site in Wombwell.
Planning permission for the construction has been secured and will allow Wakefield based Harris Construction Management Ltd to design and build the facility.
Safestyle’s current premises located on Valley Road are at capacity and offered no opportunity for further growth.
The additional space will provide the manufacturer with the opportunity for extensive growth in the future.
This includes plans to more than double the output from its operations at the site with a total investment exceeding £9m over the coming year eventually leading to the creation of 145 jobs.
Mark Scaife, Safestyle UK operations director, said: “The extension to our factory will enable us to meet future demand.
“We reported record revenue and profits in 2015 as we further rolled out our business into the South and also experienced growth in the North and the Midlands, as homeowners were attracted to our improved branding and took advantage of affordable finance packages.”
Cllr Roy Miller of Barnsley added:” We are delighted that a major plc company such as Safestyle UK has decided to reinvest in its existing site.
“This will create additional job opportunities for Barnsley. Private sector companies contribute to the economic success of the borough and are an essential part of our Jobs and Business Plan so this is fantastic news.
“We wish Safestyle UK all the best with its expansion.”
