Firefighters worked through the night to tackle a blaze at a garage and workshop in Tasburgh, to the south of Norwich.
Crews were first called out just before 1am this morning (Monday) to the fire at Ipswich Road.
Four appliances from Long Stratton, Carrow and Sprowston attended along with an aerial ladder platform, water carrier and the environmental protection unit.
A fire service spokesman said the fire had engulfed one floor of the 20m by 30m building.
One crew has recently returned to the scene to check for any remaining problems.
