On Saturday (December 5) at approximately 3.21pm, London Fire Brigade's urban search and rescue (USAR) crews were called to Uxbridge Road in Shepherd's Bush , where the roof of a shop and flats collapsed this afternoon.
A man who was walking past the building was taken to hospital by the London Ambulance Service.
A 25m cordon was temporarily put in place and adjoining buildings were evacuated as a precaution.
Station Manager Colin Parker, who was at the scene, said: "USAR crews used specialist search cameras and specially trained dogs to complete a systematic search of the building and were able to confirm that fortunately no-one else was injured in the incident."
Crews made the area safe before handing the scene over to structural engineers from the local authority.
Four fire engines and a number of specialist vehicles attended the scene.
