Peter Millman, who lives near the property, said he heard a number of explosions and saw flames around 20m high and "massive" plumes of smoke.

He and his housemates collected their important belongings - including passports and computers - and evacuated, fearing the blaze could spread to their house.

"[I] first saw it when one of my flatmates started crying out that there was a fire," he said.

He said it was the biggest fire had seen in his life.

"The scale of it ... when the explosions started, it looked like it was just going spread and spread."

He said the fire appeared to be under control now and praised the quick response from the firefighters at the scene.
