FIRE swept through a former building depot at Wombwell this morning.
It took fire crews from four stations three hours to quell the flames at the former Buildbase depot on Station Road, Wombwell.
Emergency services were alerted at 5am, and tackled the fierce blaze from above, using an aerial platform.
A spokesman for Aizlewoods Buildbase said this morning that company representatives were at the site, and a full investigation is underway.
There were no residential properties placed in danger by the fire.
Crews from Dearne, Cudworth, Tankersley and Barnsley stations attended.
