Welcome to 8047 Park Overlook, known as The Illumination House," a custom modernist renovation and addition by architect Mario Pareja and award-winning builder Galaxy Homes in the heart of Carderock Springs. The team took an original Keyes, Lethbridge and Condon-designed Pineview model and updated and opened the space to bring in an abundance of natural lighting while adding a universally-designed addition with soaring mid-century modern-inspired butterfly roof. The two-bedroom full suite addition is perfectly designed for multi-generational living, those with special needs, a nanny or home office space. Seamless indoor-outdoor living through expansive sliding glass doors, energy-efficient upgrades in insulation and mechanicals, a Brilliant Smart Home system, and so much more was added to this truly magnificent 8+ bedroom, 5.5-bathroom home over nearly 4,500 square feet (estimated) and 300+ sf garage and 120 sf playhouse on the wooded lot. The main part of the house is entered through a dramatic two-story entry foyer surrounded by a wall of glass and marked by a modernist open tread stair case. The front part of the entry level includes a bedroom with ensuite bathroom, office with a wall-mounted mid-century shelf unit and large mudroom with excellent storage and powder room with utility sink. The main level also includes a large media/family room flanked by walls of 16-feet floor-to-ceiling glass and a built-in movie projector and surround sound. A 420-square foot basement sits below the family room and is an excellent storage space or gym area. The back part of the main level includes the dining room, living room and soaring kitchen that opens to the private courtyard deck and hot tub via sliders. The kitchen was expanded and has 10-foot ceilings, walk-in pantry, skylights and floor to ceiling windows. The appliances include a Thermador six-burner stove, Thermador dishwasher and Ventahood exhaust fan. The large dual-level island that can seat eight is clad in Quartz countertops and the cabinets are Semihandmade. The backsplash and floor are tile from Porcelanosa. The custom millwork, wood art installation and floating walnut shelves are by Blake Sloane of Forty Third Place, a Hyattsville-based reclaimed wood artist. The separate wing is entered through a door in Sloanes colorful wood wall. The universally-designed suite includes ducted mini-split units and radiant floor heating throughout, two bedrooms, private balcony, an accessible bathroom and an airy living room with double-height ceiling with full kitchen. The space also has its own washer/dryer and its own access to the courtyard. The private, gated courtyard deck that connects the main house with the separate suite is made from an Ipe-like sustainable wood by Thermory. The courtyard includes a vertical garden to grow herbs, a fixed gas line grill and hot tub to enjoy the outdoors. The top level of the home includes four bedrooms (two en suite) and three full bathrooms including the private primary suite with 12-foot ceilings, walls of glass and balcony. The luxury bathroom is clad in Porcelanosa tile and has double sinks, soaking tub, separate walk-in, multi-head shower and radiant floor heat. A convenient laundry area with washer and dryer is just steps from the bedrooms. Additional key upgrades include energy-efficient Pella Proline aluminum-clad windows and doors, Brilliant smart home hub, tankless Navien water heater and solid core beechwood doors throughout. Five sliding glass doors, 11 skylights, and two solar tubes were added to bring in more natural light to the Illumination House. Sitting on a .38-acre corner lot with slate walkway, the exterior of the house is clad in a mixture of brick, Hardieplank and Atlanta white cedar open joint siding with rain screen. The extensive driveway leads to the 1.5 car garage with modernist garage door. An electric car charger is installed. Carderock Springs is a National Register of Historic Places-designated.
