One Rosslyn Mixed-Use Development

planned

One Rosslyn is a proposed three-tower, luxury mixed-use development in Arlington's Rosslyn district. The project will deliver more than 970,000 square feet of rental apartments, for-sale residential condominiums, and retail space along Gateway Park, replacing the current Rosslyn Gateway office buildings. It will include 845 residential units, a private 30,000-square-foot landscaped terrace, and over 14,000 square feet of retail space. The development emphasizes walkability, green space, and street-level retail, with expanded sidewalks, dedicated bike lanes, and numerous street trees.
