The Sustainable Tucson Ice House Lofts Shut Out Heat

The Ice House Lofts in Tucson, Arizona, are named after the previous function of the building — it was an ice factory. After being renovated to contemporary, individually unique lofts, they stayed true to their foundations and built it to cleverly (and sustainably) block out the heat. Selling from $100,000 to nearly half a million dollars, as they say, "Living in Tucson just got cooler." [Curbed]
