Situated on Old Town Alexandria's most prestigious street with Potomac River Views, this River Row Residence 217 South Union Street is one of just six newly constructed, LEED Gold-certified homes redefining luxury living along the Potomac River. Developed by the visionary JC Development, this four-level residence offers a rare fusion of refined design, advanced engineering, and an unbeatable waterfront location-with no HOA or condo fees. Crafted from solid steel and concrete and wrapped in classic brick, the residence spans 3,366 square feet and rises four stories via a private elevator. River views and architectural integrity is evident throughout-12-foot ceilings, 9-foot solid core doors, 8.5-inch white oak flooring, and expansive Andersen windows create a light-filled, contemporary interior grounded in timeless materials. The main living level features an open-concept layout flowing to a 440-square-foot outdoor terrace finished in imported Spanish porcelain tile-ideal for entertaining or alfresco dining. The gourmet kitchen is appointed with soft-close American Woodmark cabinetry, Taj Mahal quartzite countertops, and a professional-grade appliance suite: Thermador 36-inch gas range, double electric wall ovens, Bosch French-door refrigerator, Thermador dishwasher, and Sharp microwave drawer. Every detail is designed for elevated daily living and seamless entertaining. Four spacious bedrooms-each with ensuite marble-clad baths and Kohler fixtures-offer comfort and privacy. The top level opens to a 189-square-foot rooftop terrace with city and river views in select homes, enhanced by a fourth-level wet bar featuring Taj Mahal quartzite counters and a Summit beverage refrigerator. LEED Gold certification reflects the residence's commitment to sustainability and efficiency. High-performance systems include recessed LED lighting, 2-zone Goodman HVAC with Ecobee smart thermostats, electronic air filtration, humidifiers, a Rinnai tankless water heater, and a full home sprinkler system-resulting in lower utility costs and superior indoor air quality. Additional highlights include an 800 lb-capacity private elevator, integrated surround sound, Akuvox smart doorbell, multiple laundry hookups, and a lower-level family room with a second wet bar, Taj Mahal quartzite counter, and dual-zone Newair beverage refrigerator-ideal for casual gatherings or movie nights. The oversized two-car garage (21' x 20') includes a low-profile door for enhanced headroom and a Kwikset keypad entry for added convenience. Each residence comes with a California Closets credit for customized wardrobe systems. This is a rare opportunity to own newly built luxury on one of Old Town's most iconic blocks-just one block from King Street and steps from the Potomac River and waterfront promenade. With over 20 dining options within three blocks, four parks within six, and proximity to Lyles-Crouch Elementary School, River Row supports an effortless, enriched lifestyle. Commuters enjoy quick access to Reagan National Airport (3.7 miles), King Street Metro and Amtrak/VRE Station (1 mile), and key routes to Washington, D.C. and National Landing. Developed by JC Development-an esteemed firm with 25+ distinguished projects across the region-River Row is a testament to modern luxury grounded in Alexandria's historic charm. Residence 217 is more than a home-it's a landmark of thoughtful design, sustainable living, and timeless elegance.
