It's unclear when 80 new retail jobs for Ballymena will come into place.
"The Range" outlet will be situated in the Braidwater Retail Park at the former B&Q unit.
The store will feature a family café and job opportunities will be for both part-time and full-time positions in a range of areas, from warehouse assistants to store managers.
The firm said more stores in other parts of Northern Ireland were also planned.
