NEW PRICE 7/11!! Iconic NaCl House – A Modern Architectural Masterpiece Discover the award-winning NaCl House, an architectural gem designed by internationally acclaimed architect David Jameson. Located at 7405 Helmsdale Road in Bethesda, MD, this striking residence was inspired by the natural isome...tric formation of mineral rock salt. Completed in 2011, the home features a bold, Tetris-like arrangement of white stucco volumes accented with flush-glazed panels, creating a seamless integration of interior and exterior spaces. For the discerning buyer seeking a truly exceptional residence, this award-winning home is a rare opportunity to own a landmark of modern design. Honored with a 2014 Residential Architect Magazine Design Award, the property stands as a testament to modernist ingenuity and visionary craftsmanship. Inside, the approximately 4,860-square-foot residence offers thoughtfully designed living spaces centered around a striking double-height living room. This open and fluid layout invites both grand entertaining and intimate moments. Crisp white walls and light ash floors create a minimalist elegance that perfectly complement the expansive floor-to-ceiling windows and sleek glass railings. These elements flood the interiors with abundant natural light, enhancing the home’s bright and airy ambiance. The careful interplay of space and light reflects the architect’s intention to craft a home that feels both dynamic and serene. Originally built on the foundation of an earlier structure, the home was completely reimagined in 2011, blending modern elegance with structural innovation. Situated on a tranquil half-acre lot, in the sought-after neighborhood Bannockburn Estates in Bethesda, MD, the NaCl House combines architectural splendor with a serene natural setting. This exceptional property features luxurious finishes throughout, including a commanding mahogany front door and elevator, servicing all levels. Owning this iconic property is a rare opportunity to live in a true piece of architectural history - where luxury, design, and lifestyle seamlessly merge. Continue reading
