More than 20 firefighters were called to a house blaze in Melbourne’s east on Saturday morning.
Metropolitan Fire Brigade spokesman Trevor Woodward said reports started flooding in about 9.45am of flames shooting from the roof of a two-storey brick house in Slyvander Street, Balwyn North.
Mr Woodward said the house was unoccupied.
‘‘The premises had been vacant for some time and was boarded up,’’ he said.
‘‘Solar panels were fitted to the roof and crews initially had difficulty isolating the power.
‘‘The house suffered extensive damage with every room and most of the roof structure destroyed.
‘‘A neighbouring property came under threat from the intense heat but was saved by diligent work from the first fire crews to arrive on scene.’’
An estimated $700,000 damage was caused.
The cause of the fire was an overloaded circuit in the basement electrical fittings.
