The Troy Block redevelopment in Seattle’s South Lake Union encompasses an entire superblock and integrates two historic buildings. The colored glass of two modern L-shaped towers complements the vintage brick of the Troy Laundry and Boren Investment Company buildings. Gathering areas, open courtyards and artifacts from past uses of the site populate a cross-block connection. The 800,000-square-foot building—entirely leased to Amazon.com--offers 50 percent more area per floor than any other building in SLU.
