^ The Mill is awaiting redevelopment schemes, and last I checked the property was locked in MCW Holdings (the developer of the brickyard that went bankrupt) lawsuit with the City of Tempe.
The silos themselves are historically protected so there's almost no way those are coming down--I wouldnt stand for it one bit either. It is possible to renovate them into condos or whatever, so that'll likely play a big part of whatever we'll see.
The Mill parcel itself is ostensibly fairly difficult to develop--it's oddly shaped and there's almost no room for on-site parking. I think, however, that such challenges will lead to a truly unique project.
I'd like to see the following get developed:
Edits:
the 2 - 6 story stuff should be live work.
The rail tracks would be repaved with red brick, exposing the steel rails still. Historic signage and exhibits down a landscaped pedestrian path could showcase the area.
All parking structures would be underground, making this super expensive to develop.
The finishing touch--gold neon/flourescent resignage of Hayden Flour Mill on the existing tower.
Some interior photos for those not too familiar with the area (sorry if this is way off topic)
Neon lights and recessed curved windows some day?
I've always liked that fresco. Restore it!
