Arlington, VA – July 21, 2025 – Penzance, a leading owner, operator and developer in the Mid-Atlantic region for over two decades, has received approval from Arlington County for its proposed redevelopment of Ballston One at 4601 N. Fairfax Drive. The approved plan will convert the existing office building into a vibrant new residential community, adding another milestone in the company’s ongoing transformation of the Rosslyn-Ballston Corridor. Project renderings can be found here.
The new project will deliver 328 multifamily units in a 7-story building, ranging from studios to two-bedroom plus dens, as well as 13 two-story loft homes, all designed around gateway architecture with an emphasis on biophilic living and sustainability. Penzance’s plans feature the adaptive reuse of the existing underground parking garage, dramatically reducing environmental impact while supporting a thoughtfully scaled new residential structure. The project is committed to LEED Gold certification and incorporates bird-friendly glass, dark-sky compliant lighting, and a green roof to exceed Arlington County’s environmental and stormwater management standards.
“Ballston One is a transformational project that is a continuation of Penzance’s strong history of community-forward work in Arlington County,” said John Kusturiss, Partner at Penzance. “Our team is excited to reimagine this exceptionally-located property in Ballston to deliver a best-in-class residential offering that improves connectivity, walkability and quality of life for future residents and the neighborhood as a whole.”
The amenity-rich building will feature a landscaped courtyard with a pool, outdoor kitchen, and lounge areas, as well as a rooftop terrace with grills and social spaces. Indoor amenities include a fitness center, yoga studio, golf simulator, coworking lounge, makerspace, club room, playroom, and 24/7 concierge service—providing approximately 80 square feet of amenity space per unit, more than double the industry standard. The building will also feature over 130 bicycle parking spaces and 65 EV-ready parking spaces, adding to its robust sustainability features.
