Beautifully situated on a desirable corner lot in sought-after King Farm, this spacious and immaculately maintained Stanley Martin Hartwell model offers timeless architecture, an exceptional floor plan, and inviting indoor-outdoor living — complemented by a brand-new roof installed in August 2026. ++++A charming wrap around southern-facing front porch overlooks peaceful undeveloped green space, creating the perfect setting for relaxing mornings, evening conversations, and enjoying the neighborhood’s scenic surroundings. ++++Inside, hardwood flooring spans the main and upper levels, while 10-foot ceilings, crown moldings, and a dramatic staircase make an elegant first impression. Designed for both everyday living and entertaining, the thoughtfully planned layout offers an ideal combination of formal and casual gathering spaces with wonderful flexibility. ++++The main level features a spacious dining room ideal for entertaining, abundant natural light throughout, and a convenient main-level laundry room. A private first-floor office with a wall of custom built-in shelving and cabinetry creates an impressive work-from-home space, library, or study. The family room draws the eye with a wall of windows and a cozy fireplace, while the kitchen opens seamlessly to the adjoining gathering spaces for an easy, functional flow. ++++Upstairs, three spacious bedrooms each feature an updated ensuite bath and walk-in closet, offering exceptional comfort and privacy. The expansive primary suite is a true retreat, complete with a sitting room, two generous walk-in closets, and a spa-like bath. ++++One of the home’s most distinctive features is the private fourth-bedroom suite with its own separate staircase off the kitchen. With its own ensuite bath and walk-in closet, this tucked-away space is ideal for guests, an au pair, multigenerational living, a studio, or a private home office. ++++The finished lower level adds even more versatility, with generous space for recreation, fitness, media, hobbies, or play, along with a full bath and ample storage. ++++Outside, the private, low-maintenance fenced in patio is surrounded by mature trees, creating a peaceful setting with plenty of room to relax and entertain. A large patio extends the living space outdoors and provides an inviting backdrop for dining, gatherings, or simply enjoying the surroundings. ++++Residents of King Farm enjoy an exceptional lifestyle with community pools, parks, walking trails, playgrounds, tennis courts, shopping, dining, and a convenient shuttle to the Shady Grove Metro. Ideally located near I-270, the ICC, and Route 355, this home offers an outstanding combination of space, flexibility, convenience, and classic style in one of Montgomery County’s most desirable communities.
