The family was at home and heard something sounding like an explosion.
That's when they saw the old grainery turned machine shed was on fire.
Investigators believe the sound was tires popping from the extreme heat.
Firefighters from the Barlow, Chesterhill, and Wesley Volunteer Fire Departments put the fire out. First responders were concerned the house was in danger of catching fire.
The heat from the fire melted the siding right off the house. The cause of the fire is unknown.
