Several teams from Surrey Fire attended the scene. Arial footage from Chopper 9 shows firefighters moving quickly to hose down the exterior of the home.

Most of the second storey has extensive fire damage -- and most of the roof has collapsed.

Firefigthers also sprayed down the roofs of several neighbouring houses on the block as a precaution against the fire spreading to other homes. 

It is not known if any of the residents were inside the home when the fire started.

The cause is still under investigation.
