An Independent School • Grades 5-12

Established in a sleepy section of north Seattle over a century ago, Lakeside School is now centered in a busy residential neighborhood that is growing along with the city and region. 

Lakesiders and neighbors of Lakeside, please check this page for updates on construction and other news that impacts our campus and the surrounding area. 

Construction and Neighborhood News

Closure of 145th Street

Updated Sept. 18: The City of Shoreline is currently engaged in improvements along 145th St. (which borders the north end of our Upper School campus). Construction during phase 1 of this project, anticipated to wrap up this winter, impacts streets near the school, affecting travel to and from Lakeside. When complete, the project will improve safety, traffic congestion, and multimodal access along the 145th St. corridor and help connect Lakeside’s campus to the new light rail station. Read more about the projects on the City of Shoreline webpage and see a map of the affected area.

Construction at the Upper School

In fall 2026, Lakeside Upper School will have a new two-story academic building located on the field that is on the southwest corner of campus, next to Allen-Gates Hall. It will feature high-quality learning spaces, worthy of the excellence of our students and faculty; 12 English and humanities classrooms and eight biology, physics, and chemistry/advanced science labs; a wide variety of community spaces for collaboration and fun; and outdoor spaces for learning and community-building that will knit the building into the Upper School campus. 

Site preparation began in summer 2024. We anticipate opening the doors to classrooms at the start of the 2026-2027 school year!
