What Destroyed Godric's Hollow?

I've always wondered what happened to Harry's
parents' house in Godric Hollow. Apparetnly, it was completely
destroyed. Of course, it could have been destroyed by Voldemort's
failed and misdirected Avada Kedavra. But lately I've noticed that 
failed curses generally don't do that
sort of thing.  <snip>

Now me:
Yes, but was LV's Avada Kadavra 'miss directed'?  Dumbledore's full 
curse hit the desk, LV's in Godric's Hollow hit Harry first, its 
target, and failed. Perhaps the excess energy did rebound into the 
house and destroy it but it doesn't seem likely to me. An exploding 
desk is very different from a house being completely destroyed.
 
I firmly believe there was at least one other person at the house 
with the Potter's and LV that night. I think one of them destroyed 
the house in an attempt to finish off what LV failed to do, kill 
Harry. Remember we need a witness to retell the story of really 
happened in Godric's Hollow that night.

But that's all for now as I know this has been discussed before,
