A unit has been destroyed by fire and neighbours evacuated at Dudley on Tuesday morning.

Eight Fire and Rescue NSW crews arrived at the scene after 8:30am, finding flames and smoke pouring from the windows of a unit.

They quickly managed to contain the fire, though the home could not be saved.

No one was home at the time, and no one was injured in the incident.

It’s unclear what ignited the blaze, but police and fire are investigating.
