Reports suggest that it cause quite a stir across the vicinity.
The building, in Hounslow High Street, is being demolished to make way for a housing development.
According to Demolition News, Lincolnshire-based contractor GBM Demolition suspended work pending arrival of an inspector from the Health & Safety Executive to investigate the unplanned collapse.
It appears to have been only through good fortune that all debris remained within the perimeter of the site and no one was hurt.
