About 15108 Cosmos Ct

This property sits on a quiet cul-de-sac in Rockville's desirable Flower Valley community. It's a rare find with exceptional square footage, a sun-filled layout, and an impressive list of features that's hard to match at this price point. Flower Valley is known for its strong sense of community and access to well-regarded Montgomery County schools, including Flower Valley Elementary, Earle B. Wood Middle, and Rockville High. If you've been waiting for an opportunity with real upside, this is it. The main level offers a spacious and flexible layout with distinct areas for gathering and relaxing. There's a galley-style kitchen with a breakfast room for casual meals, a family room with a wood-burning fireplace, and a study off the foyer, giving the whole space an easy flow. You'll also find a spacious living room and separate dining room for more traditional entertaining. The main level features hardwood floors throughout the living room, dining room, study, and family room, while the upper-level hallway and four bedrooms feature newly refinished hardwood floors. The primary suite includes a large custom walk-in closet that was converted from what used to be a sitting room, giving it a scale you don't often see. Recessed lighting, ceiling fans, and central vac round out the interior. Off the back of the house, the owners added roughly 1,000 square feet of additional living space. It's a bright sunroom addition with skylights, a half bath, and wiring for surround sound, making it well suited for entertaining, relaxing, or creating a versatile gathering space. Below it, an equally large unfinished workshop offers exceptional flexibility for hobbies, woodworking, projects, storage, or future expansion. Existing workbenches, cabinetry, and ample workspace make it especially appealing to hobbyists and woodworkers. The .45-acre lot gives you plenty of room to enjoy outside too. There's an in-ground pool with a poolside kitchen island and Viking grill, a fully fenced rear yard with a sprinkler system, and a 20x12 storage shed for extra equipment or gear. For tennis enthusiasts, the nearby Flower Valley Swim & Racquet Club also offers community tennis courts. The home offers three HVAC zones, two 200-amp panels, and a 25kW liquid-cooled whole-house generator. There's also a two-car garage. Bring your vision and make this property your own.
