A New Chapter for the Rosslyn Skyline
ONE Rosslyn will be defined by exceptional design, world-class amenities, and neighborhood-serving retail. Positioned prominently along the Rosslyn skyline with breathtaking views of Georgetown and Washington, D.C., this new mixed-use community will blend the serenity of the Potomac’s natural landscapes with the modern vibrancy of Arlington’s most connected neighborhood.
Three architecturally distinct towers — unified by a 30,000-square-foot private landscaped terrace — will bring together the best of urban living and nature. This is more than a residential project; it’s a new vision for how people live, work, and relax in the heart of Northern Virginia.
ONE Exceptional Vision, ONE Extraordinary Team
Developed by Penzance, ONE Rosslyn builds on a proven legacy of success in Arlington. Following the award-winning Highlands development in West Rosslyn, Penzance continues its mission to “leave everything better than we found it.”
Their goal here is to create a landmark community that not only enhances the skyline, but also strengthens Rosslyn’s walkability, housing diversity, and connection to the outdoors. From its architectural design to its commitment to sustainability, every detail has been crafted to elevate daily life for residents.

Open Space and Design
The project’s signature 30,000-square-foot terrace acts as a green oasis above the shared podium — featuring garden rooms, shaded seating, walking paths, and event spaces that tie the towers together. Penzance has partnered with world-class architects and landscape designers to bring this multi-layered environment to life.
The architecture itself balances sleek modern lines with natural materials and warm tones. Every angle of ONE Rosslyn has been designed to catch light, frame a view, or invite connection.
Sustainability and LEED Gold Certification
ONE Rosslyn will pursue LEED Gold v4 certification, reflecting a deep commitment to sustainability and energy performance. Each building will incorporate high-efficiency systems, water-saving fixtures, stormwater management, and EV-ready infrastructure.
This means lower operating costs for residents, improved indoor air quality, and a healthier, more resilient community for decades to come.
