A new, additional school building will be constructed on the site of the existing Stephen Decatur school. Thornton Creek School, which is currently housed in the Decatur building, will move to the new building when it is complete.


$42.8 million

Project Description

The new school will be approximately 92,500 square feet and will accommodate up to 660 students. It will house small learning communities that include individual classrooms surrounding an open-shared learning area. Shared learning space will be found between classrooms and other space will be used for special education, art, science, music, childcare, library and gymnasium.

Seattle Public Schools plans to preserve the existing building on the Stephan Decatur School site to address projected elementary school enrollment in northeast Seattle. The school will be occupied during construction of the new Thornton Creek School.

Construction Methods

The building will be constructed using concrete spread footings and stem walls, structural steel and light gage metal stud walls for future adaptability, masonry veneer and fiber cement rainscreen cladding, fiberglass windows, aluminum storefront and curtain wall glazing, and a built-up roofing system. Interior finishes include acoustical ceiling tile, painted gypsum wallboard, built-in casework and carpet, resilient tile and ceramic tile flooring. Site development will include natural turf ball fields, hard and soft play areas with play equipment, landscaping and new curbs and sidewalks around portions of the site.

Sustainable Features

Energy efficiency will be achieved through daylighting, using high performance windows with low-e coatings, a geothermal system with heat pumps, and use of LED light fixtures with lighting controls.
