Open House on 10/12 is canceled! Step into the Theodore Sonnemann Sr. House, a distinguished 1906 residence that gracefully blends historic character with modern updates throughout. Set on over a third of an acre of manicured gardens and expansive yard space, the property enjoys a rare sense of serenity, seamlessly extending into the verdant landscape of the adjacent park. Inside, exquisite architectural details reveal themselves at every turn—soaring 9.5-foot ceilings, elegant pocket doors, and finely crafted millwork. The main level unfolds with a welcoming enclosed porch, a grand foyer, and an expansive formal dining room framed by bay windows and intricate dental molding. A gracious living room, intimate family room anchored by a wood-burning fireplace, full bath, and mudroom with direct driveway access ensure both elegance and ease of daily living. At the heart of the home, the gourmet kitchen dazzles with a marble-topped center island, high-end stainless steel appliances, and abundant custom cabinetry. The second floor is home to four well-proportioned bedrooms and two full baths, including the primary suite with an ensuite bath and a connecting fourth bedroom—ideal as a nursery, dressing room, private study, or an additional guest bedroom. The third floor offers an additional spacious bedroom and exciting potential for future expansion, while the unfinished lower level provides generous storage and laundry facilities. Nestled within the Village of Martin’s Additions, this home captures the essence of small-town charm with cosmopolitan access. Just blocks away, neighborhood favorites like Brookville Market, Olympia Café, and Le Ferme Restaurant create a lively village center. Seasonal farmers markets, weekend food trucks, and cherished traditions—from Fourth of July parades to Halloween festivities—foster a strong sense of community. All this, within easy reach of downtown Bethesda, Washington, DC, and the Capital Beltway, makes the Theodore Sonnemann Sr. House a rare offering of timeless grace in one of Chevy Chase’s most beloved enclaves.
