About this home

Situated on a private, one-acre lot in the coveted Langley Forest neighborhood, 904 Mackall Avenue is a substantial McLean estate offering approximately 9,100 finished square feet across three well-designed levels. Thoughtfully planned for both grand entertaining and everyday living, the home features six bedrooms (five on the upper level and opportunity for a main level primary or guest suite), five full baths, two half baths, two laundry rooms, four fireplaces, a three-car garage, and an elevator servicing all levels. A welcoming two-story foyer with a sweeping curved staircase introduces the home's light-filled interiors, highlighted by 10-foot ceilings, and substantial millwork throughout the main level. Formal spaces are well balanced, including a gracious dining room and a sunken living room with a masonry fireplace and Juliet balcony. Two distinct main-level office/library spaces provide exceptional flexibility. A front-facing sunroom with soaring ceilings functions beautifully as a sitting room or workspace, while a separate library/guest suite includes a walk-in closet and full five piece bath-ideal for main-level living or private guest accommodations. The heart of the home unfolds across the rear, where a spacious family room with fireplace opens seamlessly to the kitchen and breakfast area. A large center island, walk-in pantry, butler's bar, and direct access to a balconey with a gas grill create an ideal environment for both daily living and entertaining. A secondary rear staircase, mudroom, and main-level laundry add convenience and functionality. Upstairs, the primary suite is a true retreat, featuring a fireplace, tray ceiling, expansive dressing room, dual walk-in closets, and a spa-inspired bath. Four additional bedrooms are generously sized and well arranged, with a combination of en suite and adjoining baths, as well as a second upper-level laundry room. The open-to-foyer design enhances light and architectural interest. The walk-out lower level is designed for recreation and wellness, anchored by a rare indoor exercise pool. Additional highlights include a large recreation room with a fireplace, home theater, a sixth bedroom with full bath, and multiple unfinished storage/utility areas offering flexibility for future customization. Outdoor living is equally compelling, with multiple balconies and entertaining spaces overlooking the private, landscaped grounds. The three-car garage and elevator access to all levels further enhance ease of living. Ideally located just minutes from downtown McLean, Tysons, and Washington, DC, this offering presents a rare opportunity to own a well-scaled, amenity-rich residence in one of the area's most sought-after neighborhoods.
