Lewis completed the redevelopment of the historic Federal Reserve Bank in Downtown Seattle, expanding the building by seven levels for a total of 13. Work included historic preservation of the 1950 exterior and features such as the lobby and massive vault/doors, while substantially expanding the structure through every level using structural steel and concrete intricately installed amidst the existing structure. The upgraded garage holds 18 cars on one level below-grade. Light wells along Second Avenue illuminate the basement. Overall, the building is 223,000 square feet, including 156,000 square feet of offices.
