Nestled on one of Carderock Springs' most coveted lots, this exceptional mid-century modern residence seamlessly blends architectural significance, modern comfort, and extraordinary privacy. Originally designed as a Hillcrest model, the home has been thoughtfully renovated and expanded to create a spectacular open-concept living environment where walls of glass frame serene woodland views and every room feels connected to the surrounding landscape. Set on a beautifully landscaped .38-acre lot backing directly to protected parkland, the property enjoys a level of privacy rarely found in the neighborhood, with no home directly behind. Surrounded by mature trees and natural beauty, the setting offers the feeling of a private woodland retreat while remaining just minutes from downtown Bethesda and Washington, D.C. The heart of the home is the dramatic expanded living room-a truly remarkable space defined by soaring ceilings, expansive windows, custom built-ins, rich hardwood floors, and a striking stone fireplace. Flooded with natural light throughout the day, the room was designed for both comfortable everyday living and effortless entertaining on a grand scale. The connection to nature continues outdoors, where an expansive rear deck overlooks a breathtaking wooded backdrop. Whether enjoying morning coffee among the treetops, entertaining guests, or simply taking in the peaceful surroundings, the outdoor spaces provide a rare sense of tranquility and seclusion. As part of the major renovation, a new, dramatic front entrance was created and marked by the custom stone and brick walkway and modernist stairs. The four-bedroom plus office, two-and-a-half-bath floor plan combines the timeless principles of mid-century modern design with the functionality today's buyer's desire. A highly sought-after two-car garage-an uncommon feature within many original Carderock Springs homes-adds convenience and practicality to the home's architectural appeal. The main floor features the expansive living-dining area and custom kitchen, primary suite, second bedroom and powder room. The lower level has two bedrooms, one full bathroom, an office space with separate entrance, den, utility/laundry room and access to the oversized garage. Located on quiet Still Spring Court, a cul-de-sac tucked away from the neighborhood's main roads, the property offers direct access to Cabin John Park trails and the Carderock Springs Swim & Tennis Club directly from the backyard. Pool and tennis club membership conveys with the property (subject to activation fee and annual dues). Recognized on the National Register of Historic Places, Carderock Springs is one of the Washington region's most celebrated mid-century modern communities, designed by renowned architects Keyes, Lethbridge & Condon and admired for its harmonious integration of architecture and landscape. The home is currently zoned for the Carderock Springs Elementary, Thomas W. Pyle Middle School, and Walt Whitman High School cluster. For commuting, the location offers excellent regional access with quick connections to major routes including Interstate 495 (Capital Beltway), Clara Barton Parkway, and nearby Maryland Route 190 (River Road), making travel into Washington, D.C., Northern Virginia, and surrounding employment centers highly convenient. Carderock Springs has community covenants and Architectural Review Committee guidelines. (Square footage is approximate and should not be used for property valuation.)
