The Google headquarters at Belgrave House, Buckingham Palace Road, SW1, was ablaze this afternoon at 1.53pm as a fire broke out on the roof terrace, reported the Telegraph. The building is also home to American Express and Vitol.
Witnesses in neighboring blocks broke news of the fire on Twitter stating the following:
"There's a tree on fire on one of Google office roof terraces across the road" wrote one.
The flames reportedly died down within a few minutes but smoke continued to pour out into the sky as firefighters on a raised platform struggled to reach the source of the flames. The blaze was finally extinguished by around 2.30pm.
A spokesman for London Fire Brigade said that no one was thought to have been hurt in the incident.
"We were called at 1.53pm and currently have four fire engines dealing with a fire in an office building on Buckingham Palace Road," he said.
A Google spokeswoman, speaking on her mobile from outside the building, said that the cause of the fire was not yet known but that all Google staff were accounted for.
"All I know is that there was a barbecue on a roof terrace on one of the Google floors," she said.
"We have all been moved away from the building and we are waiting for the fire brigade to tell us when we can go back in."
The fire is the second to break out in two months with 76 Dean Street, W1, catching fire last month.
Worrying times, but maybe just as concerning is the speed of the helicopters movements in the video of the fire crews fightingthe blaze!!
