More than 50 jobs could be created over three years after DIY firm KDA moved to new premises in Dodworth.
Cliff Tibble, who started his business on a market stall, has bought a 64,000 square feet unit on Fall Bank Industrial Estate.
He said he will need employees to replenish shelves, for stock rotation, admin roles, and the logistics side of things.
Cliff, a former miner at Dodworth Colliery, said: "I believe the number of jobs will increase to more than 50. The location we are in is brilliant - there is nothing towards Newcastle, or the east coast or Nottingham.
"So it's going to bring income into Barnsley. It's a positive thing for Barnsley."
He has moved the business 100 yards from a rented unit.
KDA grew after Cliff started out as a market trader.
He spent £1,500 on stock and £4,000 on a van to make sure he could get to various markets.
