Tucked away on a tranquil, lofty, private drive that backs directly into the lush expanse of Rock Creek Park, 4218 Blagden Avenue NW is breathtaking, a fusion of nature and high design. Originally a traditional 1968 split-level, this residence was meticulously reimagined by the award-winning HxH Architects (Jen Harty and Albert Hopper) into a sun-drenched, contemporary "treehouse" that emphasizes light, volume, and seamless indoor-outdoor living. HxH Architects transformed the home by removing most interior walls and traditional colonial details to create an expansive, open-plan main level. The living area features preserved and reclaimed wood ceiling trusses that elevate the sight lines and draw the eye toward the surrounding parkland views, using a sophisticated palette of rift-cut white oak cabinetry, custom wall panels, and a contemporary cedar garage door, that harmonizes the home with the natural surroundings. The repositioned floor plan includes main floor laundry and three spacious bedrooms on the entry level, including a peaceful primary suite with woodland views. The large French doors lead to an Ipe wood landing and patio, perfect for private alfresco dining under the forest canopy. Features panelized, concealed appliances for a sleek, modern aesthetic and a large island designed for entertaining. A daylight-filled lower level offers a generous family room with a gas fireplace, a full bar with wine storage, and a functional mudroom with built-in storage. This home is a rare opportunity to own a designer sanctuary that feels miles away from the city while being just minutes from the best landmarks and amenities in DC.
