Computers and office appliances were among items said to have been destroyed in the inferno.
The fire was said to have started barely 20 minutes after Obasanjo left the house for an undisclosed place. He was however said to have hurriedly returned to his burning building to supervise those fighting to quench the fire.
His wife, Bola, children and grandchildren, said to be on holiday, were reportedly moved to safer sections of the mansion as the fire raged.
A source said one of the aides to the retired general noticed smoke bellowing from a section of the mansion about 4.10pm.
The aide was said to have raised the alarm to attract the attention of other occupants of the building, including security officials, who quickly moved to stop the fire from spreading to other part of the house.
The raging inferno however got out of hand and the State Fire Service and the Nigeria Security and Civil Defence Corp were called in for help.
