Benjamin Banneker High School

The new high-performing, flagship high school was designed to facilitate academic excellence for students in Washington, DC. DGS’ Benjamin Banneker High School provides a 21st-century learning environment to accommodate an increased enrollment of 800 students by 2025. The design envisioned a series of interconnected spaces for learning, discovery, and engagement. The project’s program included an open atrium and learning commons; classrooms with ample natural light; gym, auditorium, and cafeteria for active community use; collaboration areas to enhance communication and activate interdisciplinary learning; coffee shop, science labs, studio and performing arts spaces, and outdoor learning areas. The building is topped with an intensive green roof.

Banneker High School was designed to be the first Net Zero Energy school in Washington, DC. The high-performance learning environment serves as a teaching tool for staff and students, while positively supporting their health and education. The building achieved LEED Platinum under LEED v4 BD+C Schools in 2023.

Stanton Elementary School

Project scope included the complete upgrade of all mechanical, electrical and plumbing systems of the 60,000 SF existing main school building, as well as the design of a 30,000 SF new addition. The project design supports a LEED Gold rating, based on LEED 2009 for School New Construction and Major Renovations. A fast-track design and construction schedule enabled the 60,000 SF first phase to be completed over the summer in time for the start of school in the late August.
