The Weyerhaeuser Corporate Headquarters in Federal Way, Washington is one of the most iconic projects bringing architecture and landscape together. The current owners of the site, Los Angeles-based Industrial Realty Group (IRG), have shared plans to clear-cut 132 largely forested acres on the 425-acre campus to build 1.5 million square feet of warehouses. Now the group is facing pushback from architects, preservationists and landscape architects across the country.
