Car Crashes Into Factory Roof After Veering Off Road

A driver has miraculously escaped with barely a scratch after spectacularly crashing into the roof of a building in Sydney's inner-west.

Emergency services have asbestos fears, after the car plunges six metres off the road and in the roof of the auction house on Hill Street, Leichhardt, at about 2.45pm on Monday.

It is not clear what caused the crash. The driver is said to be a man in his 30s.

No one was injured in the crash and the building was evacuated after fears the building would collapse, NSW Police told 10 daily.

The car is believed to have gone through the intersection of Hill Street and Emma Street, crashing through a wooden fence and landing in the roof of the building, which is below street level.

Witnesses told 10 News First they saw the driver crawl out of the car and make his way on to the street, but appeared to be suffering from shock.

"I was working from home...and there was a massive bang, and I just assumed that somebody might have side-clipped a car or there was falling timber," local resident Sarah Hardie told 10 News First.

"And then the sirens started coming and I thought 'maybe there was an explosion', and become came rushing out and everyone just kept saying 'there's a car, there's a car, it's gone off the edge',"

The driver was treated at the scene and is assisting police with their inquiries.

The auction house, Raffan Kelaher & Thomas Auctioneers posted a photo of the crash on their Instagram, calling Monday an "eventful" day.

"We are very lucky that no one was hurt - but it does mean there will be no auction tomorrow!" they said.

"Deliveries this week will also be affected."

The car remains in the roof, supported by a steel beam, and a crane has been brought in to remove it.

However, emergency services have confirmed to 10 News First there are now asbestos fears.
