About 10 people had to be evacuated from buildings close to a garage fire in a city centre.
The blaze at a workshop, used for vehicle repairs and bodywork, in Old Redbridge Road, Southampton, started at about 06:40 GMT.
About 50 firefighters tackled the blaze, which destroyed the building. It was brought under control by midday and there no reports of any injuries.
Road closures and a 200m (660ft) police cordon have since been lifted.
Hampshire Fire and Rescue Service said crews were able to stop the fire spreading to surrounding buildings.
It added one crew would remain at the site to continue damping down.
The service said its investigation into the cause of the fire was ongoing but not believed to be suspicious.
At the height of the blaze, a thick, black plume of smoke could be seen for miles around the city.
Those living or working nearby had to keep their doors and windows closed as smoke drifted from the fire.
