Difficulties accessing a steady water supply hampered firefighting efforts at a two-storey Lanena Crescent property just south of Exeter.
The Tasmania Fire Service was called to the property just before 2pm and had to call upon the services of further tankers in order to get on top of the blaze.

There was no water supply at the property and fire trucks had to ferry water up a steep dirty hill of only one lane.
Tamar District acting-station officer Jeff Gibson said the fire was one of the most difficult he had been involved in. Several hours after fire crews first attended the property, the top storey was still alight and smoke was seeping from the heat-buckled tin roof.
Mr Gibson said a neighbour called the fire in following an attempt to get it under control that was foiled by rising temperatures.
A total of seven fire fighting vehicles and as many as 30 volunteers were called upon to get the fire under control. Volunteer crews from Gravelly Beach, Legana, Kelso. Winkleigh and Glengarry joined in to help get on top of the blaze.
Investigations into the cause of the fire were expected to start from Saturday morning.
