Demolition. Not long before this, kids made ad hoc use of the derelict building for skateboarding etc.  Angry boys?!  (Angry Boys on ABC TV from Chris Lilley with HBO as co-producer and pre sale to BBC.  Whatever will they make of the series?)  

On another tack, is it quaint to see the Latin term, ad hoc used in a question on today's census form?  Ques 49... Ad hoc help or assistance, such as shopping....

From Macquarie Dictionary: ad hoc: 2. impromptu. An ad hoc decison is one made with regard to the exigencies of the moment.
