100 jobs are to be created in Tuam, Co Galway, between now and the end of 2017 as Steeltech Sheds plans to relocate to a new base there.
The company says the new jobs will be created as it expands its market into the UK and mainland Europe.
The firm's main operation in Galway is currently based on the Headford Road.
This centre will be moved to the former Cola-Cola plant base in Tuam.
Steeltech Sheds currently employs up to 100 staff at bases nationwide including Cork, Dublin, Carlow and Athlone.
The company says it is recruiting new staff on an ongoing basis.
