Tucked into one of Washington DC's most unique and private enclaves, this extensively renovated mid-century modern retreat offers a rare opportunity to own what feels like a true treehouse in the heart of the city. Located on a quiet street of just six homes in coveted Forest Hills/Cleveland Park, directly across from the Smithsonian National Zoo and moments to Rock Creek Park, this architectural showpiece blends privacy, nature, and sophisticated entertaining in a way few Washington properties can. Surrounded by mature trees and with soaring ceilings and walls of glass, the home feels worlds away while remaining minutes to the White House, United States Capitol, Embassy Row, downtown Washington, and major international institutions. Designed for both elegant entertaining and comfortable daily living, the home has been thoughtfully transformed with extensive renovations valued at over $500K including removed walls, reconfigured living spaces, and a relocated fireplace to create an open, modern layout filled with natural light. Infused with countless high-end upgrades and designer finishes both big and small, the floor to ceiling stone fireplace, rich hardwood flooring, custom woodwork, chic upgraded lighting, sleek renovated baths, and so much more create instant appeal. The dramatic rear elevation showcases expansive windows overlooking the trees, multiple outdoor entertaining spaces including two rear decks, a stunning stone patio with fire pit, and a welcoming enclosed front porch and front stone terrace ideal for hosting guests or quiet evenings outdoors. Offering over 3,500 finished square feet, the home includes a luxurious upper-level primary suite with a private balcony and a renovated ensuite bath with a vessel soaking tub and dual showers, a lofted office or lounge space, and additional finished storage area. The lower-level features two additional bedrooms, a renovated full bath, and a spacious family room with direct access to the outdoor entertaining spaces. The seller has made extensive renovations both inside and out and sadly has to relocate. Complete with a two-car garage, this exceptional residence is a rare offering for diplomats, international buyers, executives, or anyone seeking a private architectural retreat in one of Washington DC's most prestigious and globally connected locations.
