The outbuilding caught fire on Sunday night.
Fire crews from Exmouth and Budleigh Salterton were called to Littleham Road just after 11.10pm last night (Sunday 15th September)
They say the 6m x 4m building was "well alight."
By midnight, Western Power were requested due to arcing cables.
It took until the early hours of this morning (Monday 16th September) for the fire to be completely extinguished.
It's believed to have started accidentally.
