Emergency crews found the body of the person, who is yet to be formally identified, inside the burnt home at Merriwa on Wednesday.

It came after firefighters were called to a rural property on Mountain Station Road about 9.15am after reports that a house was engulfed in flames.

Rural Fire Service and Fire and Rescue NSW teams spent several hours putting out the blaze.
