Exciting Update: Our New School Building Project!

We are thrilled to share the latest updates on our new school building! This project marks a major milestone for our community, and we can’t wait to welcome everyone into this bright, spacious, and inspiring environment.

A Space That Inspires
Our new building is designed with students, staff and sustainability in mind. Filled with natural light and open spaces, it will foster creativity, collaboration, and learning. From dedicated classrooms to flexible meeting areas, the layout is intended to support a variety of learning styles and needs, providing a comfortable and dynamic space for all.

What’s Happening Now?
Our department leaders have been hard at work planning the interior space and furniture layouts. We’ve already had a successful tour of the building, and families will soon have the chance to see the progress through a slideshow at PTSA meetings (join us online!).

Stay Connected
We are excited about what’s to come and will continue to provide updates as the project moves forward. Thank you for being part of this journey with us as we build a future-focused space for our students, staff, and community.

(Updates are posted for the previous month after the BEX/BTA Oversight Committee Meeting. The committee does not meet in August so there is no July update.)

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.
