The Icehouse is a great example of adaptive use in downtown Phoenix. From it's origins producing ice used to ship produce farmed in the Valley by rail to eastern consumers, it has be resurrected as a multi-use space.
While first and foremost an art gallery -- and it's diversity of interior and exterior spaces make it a great place for large scale installation work as well as more intimate showings -- it is also a unique space for all sorts of events from indie rock concerts to corporate fundraisers (and would make an AMAZING place for a wedding ceremony and reception!)
