Completion Date


ATSR created a STEAM addition for an existing urban campus. The addition made a flowing connection between two existing buildings set at multiple levels. The double-story commons is the new hub of the building and is filled with natural light and takes advantage of beautiful views overlooking the nearby Mississippi River.

Students can work collaboratively in small group rooms or break out into a variety of seating arrangements in the commons and the overlooking balcony. Transparency and overhead doors create connections between classrooms and into the commons.

The addition includes five science labs, two art studios, maker space, classrooms, administration, student commons, staff lounge, and school chapel. Math classrooms are nearby in the existing building.
ATSR provided architectural, mechanical, electrical, technology, interior design, and construction administration services. During the planning phase, ATSR gave tours of existing schools to test concepts in educational design with the staff, students and overseeing committee. Interactive computer models were used to develop and visualize the design options.
