A permanent building is underway for School in the Woods, an environmentally focused academic program for fourth-graders in Academy School District 20.
A ceremonial groundbreaking was held Wednesday, at the 640-acre site in Black Forest.
The building will replace modular trailers and house 78 fourth-graders from across the district, as well as some third- through eighth-grade home school students.
It's scheduled to open next fall.
The project is part of a $230 million bond authorization voters approved in November 2016.
This is the third new construction project to kick off since the proposal passed. A new elementary school and a new middle school also are in the works for the fast-growing district that covers northern Colorado Springs.
The new, single-story School in the Woods, located on a large parcel of a relatively undisturbed ponderosa pine ecosystem, will feature open learning labs, a "Curiosity Center," a demonstration kitchen, an outdoor patio and flexible space.
The design, by RTA Architects of Colorado Springs, focuses on natural materials that will enable students to feel immersed in the environment.
Students learn through interaction with living systems and the outdoors, and are taught about sustainability, exploration and the study of natural sciences, along with core subjects.
