The award-winning NaCl House, a landmark of modern residential architecture designed by internationally acclaimed architect David Jameson, has been listed for $3.795 million. This distinctive home is in Bethesda’s prestigious Bannockburn Estates and offers an extraordinary opportunity to own a true piece of architectural history.

The residence is listed by Wendy Banner at the One Bethesda office of Long & Foster Real Estate, an exclusive member of Forbes Global Properties. Located at 7405 Helmsdale Road, this 4-bedroom, 4 full and 1 half-bathroom residence spans over 4,000 square feet of luxurious living space situated on a tranquil half acre lot.

“The NaCl House is not just a home, it’s a living sculpture,” said Banner. “It offers a unique opportunity for the discerning buyer who values world-class architecture, modern design, and a tranquil setting just minutes from downtown Bethesda and Washington, D.C.”

Completed in 2011 and inspired by the natural isometric structure of mineral rock salt, the NaCl House features a bold composition of interlocking white stucco volumes punctuated with flush-glazed glass panels. This sculptural design allows for a seamless integration of interior and exterior living spaces, exemplifying Jameson’s vision of architectural transparency and harmony with nature. The home received a 2014 Residential Architect Magazine Design Award, underscoring its status as a benchmark of contemporary design.

At the heart of the residence is a dramatic double-height living room that anchors the open-concept layout. Minimalist interiors feature crisp white walls, light ash flooring, and floor-to-ceiling windows that bathe the space in natural light. Sleek glass railings and floating staircases further enhance the home’s refined modern aesthetic.

Originally constructed on the foundation of a previous structure, the home was completely reimagined in 2011 with state-of-the-art materials and systems. Premium features include a commanding mahogany front door, elevator access to all levels, and luxurious finishes throughout.

The property is located near top-rated schools, parks, and premier cultural and retail destinations, making it both a serene retreat and a connected lifestyle hub.
