Fulton Market District

This guide to the Fulton Market District in Chicago starts with a puzzle: what do you do with a ten-story building frozen solid, floor to ceiling, after decades as a meatpacking cold-storage warehouse? It follows developer Sterling Bay's 2012 purchase of the building, the ammonia lines and cork insulation that had crept ice into its concrete bones, and the slow, floor-by-floor thaw crews had to manage before construction could even begin. Look up at the glass-walled tower now standing where that icebox once stood, on a block still lined with the district's old meatpacking warehouses.
