About 30 people were moved out of their homes after a fire broke out at a West Midlands supermarket.
Up to 40 firefighters tackled the blaze at K2 supermarket, in Claremont Road, Smethwick at about 0100 BST.
A West Midlands Fire Service spokesman said the roof and the first floor of the two-storey building collapsed onto the pavement and road.
Roads in the area were closed for most of the day and police said "significant disruption" had been caused.
Telephone mast collapsed
Two elderly women, who lived nearby, were checked over as a precaution by paramedics.
West Midlands Police said the people who had to move were taken to the Windmill Centre for safety until the fire had been put out.
Insp Bal Mand said it was a serious fire which had totally destroyed the building and caused significant disruption to people living nearby.
High Street, Claremont Road and Cape Hill were amongst the closed roads which reopened at about 1730 GMT.
The spokesman said the building was a brick-built mid-terraced shop with other shops on either side and accommodation above.
He said a telephone communications mast, which was on the roof, also collapsed.
Gas and electrical engineers have been at the scene to isolate the building's supply once debris has been cleared.
A council structural engineer has attended to assess the building.
