Firefighters have successfully defended a Goolwa house from fire after an outbuilding on the property caught alight on Wednesday morning, October 27.
Country Fire Service (CFS) spokeswoman Danielle Blanch said fire crews were called to Port Elliot Road just after 10am, having received reports of a house fire.
Three CFS trucks with 15 firefighters on board attended, along with two Metropolitan Fire Service truck crews, to battle the blaze.
The building, containing a bathroom and laundry was fully alight upon their arrival.
"The outbuilding, around 40 square metres in size, was completely destroyed by the fire," Ms Blanch said.
"However, crews were able to successfully defend the main residence with some fire impact to the external verandah."
SA Ambulance attended to treat a bystander at the scene for smoke inhalation but they did not require hospitalisation, and no one else was hurt.
The total damage bill is in excess of $100,000.
Gas bottles next to the house were impacted, but it is unknown if they were involved in the initial ignition.
A cause is yet to be determined, and fire cause investigators will be attending.
