Forensic crews are investigating after a fire destroyed a house in North Lambton this morning.
Emergency crews were called to the Newcastle Road property about 6.50am today and found the house engulfed in flames.
A primary search of the house found that nobody was home at the time of the fire.
It took firefighters about 1.5 hours to extinguish the flames.
A NSW Fire and Rescue spokesman said residents from neighbouring properties were evacuated.
Eastbound lanes on Newcastle and Main roads were closed earlier today.
The cause of the fire is not yet known and investigations are continuing.
