Thirty five firefighters are currently trying to extinguish a barn fire in Shillingstone, North Dorset.
Six fire engines, a Land Rover and a water carrier are involved in trying to get the fire under control.
The fire broke out shortly after 10am in a two-storey barn. It then spread to a single Dutch barn.
A spokesperson for Dorset Fire and Rescue said there were concerns about the stability of the building and they had asked a council building inspector to attend.
They also advised nearby residents to shut their windows to keep the smoke out.
