T3 Goose Island is a six-story, 275,000-square-foot heavy timber office development. The project will be the first wood-structured office building developed in Chicago since the 1800s. Goose Island, an industrial and manufacturing hub since the 1850s, is now being reinvented as a highly desirable office location surrounded by the most affluent residential neighborhoods in Chicago. Sparked by the North Branch Framework, approved by City Council in July, the plan includes infrastructure improvements, added public, pedestrian and bike-friendly transit options, and open space to take advantage of Goose Island’s natural setting on the Chicago River. Until 2015, the T3 Goose Island site was home to Big Bay Lumber.
