Iconic NaCl House – A Modern Architectural Masterpiece Discover the award-winning NaCl House, designed by internationally acclaimed architect David Jameson. This striking residence, completed in 2011, offers a rare opportunity to own a landmark of modern design in the highly coveted Whitman School District. Honored with a 2014 Residential Architect Magazine Design Award, the property stands as a testament to modernist ingenuity and visionary craftsmanship. Set on a tranquil half-acre lot in Bannockburn Estates, the home spans approximately 4,860 square feet and features a light-filled, open layout centered around a dramatic double-height living room. With extra-tall ceilings throughout, the interior feels expansive and airy. Crisp white walls, floor-to-ceiling windows, and light ash floors enhance the home’s bright, modern ambiance. The first level also includes two versatile home offices, offering ideal spaces for work, study, or creative pursuits. A commanding mahogany front door and an elevator servicing all levels add to the home’s sense of luxury and ease. Beyond its architectural significance, the residence delivers everyday convenience—just minutes to I-495, downtown Bethesda, and Washington, DC—making it as functional as it is stunning. This is a rare opportunity to experience architectural history while enjoying modern comfort, flexibility, and one of Bethesda’s most sought-after locations.
