Hoffman built a pair of new middle schools for the Shoreline School District. Each new school is approximately 150,000 square feet and serves around 1,000 students in grades 6-8. Both existing schools remained occupied throughout construction and finished in time for the schools to open in August 2020. The new Kellogg Middle School project added general classrooms, reconfigured staff and visitor parking, new bus load/unload zones, a kitchen and cafeteria, administrative offices and support areas, play areas, upgrades to the tennis courts, a track and field refresh, various site amenities, and landscaping throughout the site.
