Nestled at the end of a quiet cul-de-sac in Patuxent Glen, this charming colonial offers a comfortable blend of everyday living, thoughtful updates, and outdoor enjoyment. From the moment you arrive, the home feels warm, welcoming, and easy to settle into. Inside, the traditional floor plan provides generous living spaces with hardwood and LVP flooring, custom moldings, a formal dining room, and a spacious family room with a wood-burning fireplace. The eat-in kitchen features a granite sink and countertops, stainless steel appliances, a pantry, and plenty of room for gathering. Upstairs, the spacious primary suite is a true retreat — airy, relaxing, and, private from the rest of the home. With a vaulted ceiling, large walk-in closet, soaking tub, walk-in shower, double vanity, and ceramic tile bath, it offers the kind of space that feels calm, open, and easy to unwind in at the end of the day. Three additional bedrooms provide comfortable space for family, guests, work, or hobbies, and the upper-level laundry adds everyday convenience. The outdoor space is one of the home’s most special highlights. A mature tree canopy creates a peaceful, private setting, while the rear privacy fence adds another layer of seclusion. Designed for relaxing, entertaining, gardening, and play, the yard features a cascading koi pond with three ponds, a custom playhouse, an outdoor shower, and a patio with a new 2026 gazebo. Deck and patio spaces make it easy to enjoy morning coffee, casual dinners, summer evenings, or quiet moments surrounded by nature. The yard is also wired for invisible fencing, offering added convenience for pet owners. The unfinished basement offers approximately 1,000 square feet of additional potential, with daylight, windows, interior access, shelving, a sump pump, and rough-in plumbing for a future full bath. Whether envisioned as a recreation room, home gym, workshop, media space, or additional living area, it provides valuable flexibility for the next owner. Conveniently located near shopping, dining, parks, schools, and major commuter routes, 305 Arlington Court offers the rare combination of peaceful cul-de-sac living, privacy, outdoor beauty, and everyday convenience.
