An investigation into what caused a fire on a working farm in Ormesby St Margaret is ongoing.
At its height, more than 70 firefighters were sent to tackle a building fire at Hirst Farm on Monday morning.
Two agricultural buildings at the agricultural farm off North Road, which is owned by former county chairman of the National Farmers Union Richard Hirst, caught fire, with crews getting the call at 4am.
Firefighters from around the county set up a 100m exclusion zone after propane cylinders were found on site and remained on scene throughout the day.
North Road was closed for more than 12 hours while crews dampened down hot spots before a fire investigation team arrived on site.
This afternoon, a spokesman for the Norfolk Fire and Rescue Service said the investigation into what caused the blaze was ongoing.
The cost of the damage is not yet known, but items inside the buildings included farm machinery.
