On the market for the first time in 50 years, 22509 Charlestown Drive sits at the end of a cul-de-sac in Mulwood, one of the most established neighborhoods in Calabasas. This split-level five-bedroom home spans 2,925 square feet on a 9,558-square-foot lot, with a quiet setting and room to grow. A double door entry opens into a floor plan built for both everyday living and entertaining. The formal dining room offers built-in china cabinets. The family room features a stone fireplace, wood floors, and newer double pane windows. Storage runs throughout the home. The kitchen is clean and open with plenty of cabinet space. Appliances include a KitchenAid double oven and a five-burner cooktop, all stainless steel. A breakfast nook, a pantry, and a built-in desk area round out the space. The home has been freshly painted. Downstairs offers a den with a bar and a stone fireplace, functioning as a second living area. A bathroom with a shower and a large laundry room sit on this level. One flexible room is currently set up as a home theater and works easily as a fifth bedroom or a potential ADU conversion. Upstairs holds four more bedrooms. The primary suite has a balcony and a well-maintained bath with a large walk-in closet with built-ins, a soaking tub, a separate shower, dual vanities, and a makeup area. Secondary bedrooms feature mirrored closet doors, with additional hallway storage. The backyard is low maintenance with a garden area and a view. There is room to add a pool. A covered patio opens off both the den and the downstairs bedroom, creating a quiet outdoor retreat. An updated HVAC system, updated windows, and a newer roof complete the home, along with a two-car garage with direct access. Mulwood puts residents minutes from Calabasas Commons, top-rated Las Virgenes schools, and easy 101 freeway access. A home held this long, in this location, is a rare opportunity.
