According to the Guardian, the incident occurred at around noon yesterday at the Audi dealership in Milton Keynes – a town of about 250,000 in Buckinghamshire that you may recognize as the home base for Red Bull Racing as well as Honda's F1 engine ship. (It's also where companies like Mercedes, Volkswagen, and Suzuki have placed their UK offices.)
Workers in the service department reportedly heard a bang, then evacuated the building before the roof gave way. The section of roof that collapsed apparently serves as a multi-story parking structure at the back corner of the workshop.
Firefighters responded to the scene, but fortunately no one was reported to have been injured in the incident.
