  • Location

    1771 N Street

Through the incorporation of sustainable design elements, rejuvenated outdoor spaces, and interior improvements, the 1771 N Street design team transformed the 1960s legacy building into an amenity-rich, trophy class, LEED v4 BD+C Gold office building. Designed to support occupant health and well-being, the building features enhanced indoor air quality strategies, highly efficient HVAC systems, and an abundance of natural light, courtesy of the curved glass curtain wall on the southwest façade. For 1771 N Street, the utilization of sustainable strategies reduced costs and created revenue-generating opportunities, while benefiting the local community and environment.

Located in Dupont Circle, the building’s proximity to public transportation, as well as local DC businesses and landmarks, plays an active role in supporting the economy and creating a diverse and accessible space for all. Through the collaboration of the design team, the project was designed to meet the growing needs of residents, commuters, and visitors of Downtown DC. Since the project’s completion in 2021, 1771 N Street has served as a symbol of equitable design in the local community and a model for future developments in the DC Metro area.
