Tucked within a serene cul-de-sac in Bethesda’s coveted Burning Tree neighborhood, 6605 Lybrook Court represents the latest collaboration between renowned builder Dena House and AP Architects. Recently completed on over half an acre, this custom contemporary residence spans more than 9,000 square feet across three thoughtfully designed levels, offering a rare combination of modern sophistication, enduring craftsmanship, and flexible living spaces. Defined by clean geometry and finely curated materials, the home balances sleek modern elegance with lasting comfort. The striking façade, composed of Shouldice dimensional stone and white concrete and accented by black-clad Pella windows, is approached via a custom concrete block driveway with grass in between, providing parking for up to nine cars. A dramatic 25-foot-wide staircase leads to a 300-square-foot covered terrace with a luxury mahogany ceiling, framing the glass pivot front door and soaring double-height foyer. Inside, a floating Viewrail staircase with four-inch treads and glass railings ascends before a 21-foot paneled red oak wall, creating the home’s architectural centerpiece. Expansive sightlines and abundant natural light connect formal and informal spaces seamlessly. The formal living and dining rooms flow effortlessly, while a distinguished study with custom millwork, dual built-in libraries, red oak–paneled walls, and a private exterior entrance provides an elegant and functional space for work or reflection. The informal living area centers on a family room anchored by a striking gas fireplace within a porcelain and marble surround, framed by panoramic views of the rear terrace. Throughout the main level, 7.5-inch white oak floors, Visual Comfort lighting, and Lutron smart controls create a cohesive atmosphere of sophistication. The home is equipped with Bose and Polk sound systems, with 11 speaker pairs delivering immersive audio throughout. The kitchen is both a statement and a sanctuary, featuring two-tone Wood-Mode cabinetry, Calacatta Silver quartzite surfaces, a waterfall island, a custom hood, and a full Wolf/Sub-Zero appliance suite. A butler’s pantry and walk-in secondary pantry provide abundant storage and prep space. A mudroom connects to the three-car garage and family powder room, while a main-level guest suite enhances multigenerational flexibility. Upstairs, the primary suite is a retreat of exceptional comfort, with poplar-beamed ceilings, red oak paneling, dual custom walk-in dressing rooms (one with a Taj Mahal-topped island), and a private sitting room with kitchenette opening to a screened porch with a mahogany ceiling. The spa-inspired bath features a Negresco leather granite double vanity, Tappeti marble, Badeloft soaking tub, and expansive glass shower. Three additional bedrooms, each with ensuite baths and custom walk-in closets, surround a loft sitting area, with a conveniently located laundry room. The lower level is devoted to recreation and relaxation, featuring a home cinema with 6.1 surround sound, glass-enclosed wine room, fully equipped bar and kitchenette, fitness center, and guest suite with full bath. A Savaria Eclipse elevator provides seamless access to all three levels. Outdoors, two metal pergolas define distinct gathering areas, one anchored by a natural gas fire table. Custom concrete hardscaping and lush landscaping create a private, serene setting ideal for intimate dining or larger entertaining. Smart home systems, including Ring security, Nest thermostats, and WiFi-enabled appliances, integrate convenience and efficiency into daily life. With meticulous craftsmanship, modern design, and a premier location blending tranquility with proximity to downtown Bethesda, 6605 Lybrook Court offers a rare opportunity to own a newly built residence of architectural distinction, where every detail reflects comfort, style, and timeless sophistication.
