If the building is salvageable there is no need to demolish it. Potentially affordable large open indoor spaces like this are rare, I would like to see it repurposed into something like a climbing gym, pickleball centre, indoor mountain bike course, etc. There is plenty of already empty land very nearby that can be developed into something new like student housing (Petroleum Club, Hanger 11, East end of Blatchford, etc....). Worse case scenario is its another thing demolished and turned into parking in that area.
