Why did the children demolish the house?

The children demolish the house because they could.  They do it to prove a point about themselves, that as a neighborhood gang, they were to be taken seriously.  It also becomes a matter of challenge--the boys destroy the house to prove to themselves that they had the necessary skill set and discipline to make it happen. 

The house also represents a higher social class.  Described as a "top hat" in the final scene, the house seems out of place to the children who may want subconsciously to erase reminders of a class system which has no place for them.  The destruction becomes their outlet for rebellion against the system.
