About This Home

Welcome to 43179 Mongold Sq in sought-after Loudoun Valley, Ashburn—a rare opportunity to own the coveted Delanie model penthouse end unit, where luxury meets lifestyle. With 3 bedrooms, 2.5 baths, a dedicated office, and an expansive rooftop terrace, this home is a masterpiece of style, comfort, and convenience.
The upgraded modern design package sets a sophisticated tone throughout the home. Enjoy engineered hardwood oak floors, brushed satin nickel finishes, and premium Kohler fixtures. The gourmet kitchen is truly a chef’s dream, featuring a 30” smart wall oven/microwave combo, 36” gas cooktop with canopy vent hood, quartz countertops, and a large island perfect for entertaining.
The main level also offers a spacious dining area, walk-in pantry, elegant powder room, and a bright home office with a custom built-in desk. The living room opens to a private balcony, adding even more natural light to the open-concept layout.
Upstairs, the luxurious owner’s suite impresses with double walk-in closets and a spa-inspired en suite bath. Two additional bedrooms, a second full bath, laundry room, and a cozy loft-style sitting area round out the upper floor. Head one level up to your private rooftop terrace—ideal for hosting guests or enjoying quiet evenings under the stars.
Every detail was thoughtfully curated, including $15,000 in custom window treatments, professional tinting, high-end carpeting, and a 20-inch Big Gray whole-house carbon filtration system for purified water throughout.
Living in Loudoun Valley means access to resort-style amenities—pools, parks, a clubhouse, fitness center, and scenic trails. You’re minutes from Dulles Airport, the Ashburn Metro, Route 7, and the Dulles Greenway. Plus, shopping, dining, and entertainment are right around the corner.
