About the Project

The existing Asa Mercer Middle School building will be demolished and a new mass timber multi-story middle school building of approximately 174,000 sq. ft. constructed. Once complete, the new school building will provide permanent space for 1,000 students in grades 6–8.

The new one- to three-story school will be surrounded by landscaping and outdoor learning spaces. A synthetic turf practice field is planned for the east side of campus. A new, secure entry will welcome students, families, and the community with a clearly defined “front door” to the school.

Classrooms will be organized by academic neighborhoods, with flexible support spaces to promote a sense of community and support academic success for all students.

Sustainable design features are built in to meet district goals for clean energy and renewable resources.

Funding Source: Funded by the Building Excellence V (BEX V) Capital Levy, approved by Seattle voters in 2019.

Interim Location: During construction, Mercer International Middle School will be located at the Van Asselt School Interim Site, 7201 Beacon Ave. S.
