Should Gates Rubber Factory in Denver be preserved?

Not only is it a cool sight, it is the last standing structure that represents Denver's industrial past. This was one of the largest non-tire producing rubber companies in the world. The building is currently vacant and is slated for demolition to make way for condos. In my opinion this is a rather stupid idea to tear down this building. It is a landmark!! Already 2/3 of the entire factory has been destroyed, but at least preserve the main building. It is a prominent sight of the skyline and tearing it down would be a great insult to Denver's history. Restoring this building would be a much better idea than to turn it into ugly apartments for wealthy people. My grandfather used to work in the factory from 1951 to 1974. He and many others does not want to see this piece of history go. This year is the building's 100th anniversary. In your opinion should the building be preserved or demolished?(If you have seen the place in person you may realize this is a truely beautiful sight)
