Welcome to 1077 Spring Hill Road, a thoughtfully updated residence offering the rare combination of space, efficiency, and convenience in one of McLean's most desirable locations. Situated on over half an acre within the Langley High School pyramid, this 4-bedroom, 4.5-bath home combines established neighborhood living with modern upgrades designed for long-term comfort and sustainability. A standout feature of the property is its commitment to energy efficiency and self-sufficient living. A 12.3 kW solar panel system installed in 2023 offsets approximately 80% of annual electricity costs, creating significant long-term savings. Equally impressive are the home's extensive recent infrastructure upgrades, including two new HVAC systems (2024), updated electrical panels (2023), a new all-electric water heater (2023), and a whole-house water filtration system with dedicated drinking water filtration (2023). Recent improvements also include Pella windows and sliding doors (2023) and new kitchen cabinetry (2026), providing both functionality and peace of mind for years to come. Inside, a two-story foyer with hardwood floors, crown molding, chair railing, and wainscoting introduces a home designed with timeless appeal. The formal living room features a wood-burning fireplace with brick surround and marble hearth, while the dining room offers classic architectural detailing for both everyday meals and special occasions. The family room centers around a second fireplace with stone surround and opens directly to the patio, creating seamless indoor-outdoor living. The renovated kitchen serves as the heart of the home, featuring new cabinetry, abundant storage, stainless steel appliances, a center island, and a breakfast area with direct access to the outdoor living spaces. A private office, mudroom with utility sink, laundry area, and direct garage access enhance the home's everyday functionality. The upper level features a spacious primary suite with a walk-in closet, private balcony, and en-suite bath complete with a double vanity, soaking tub, and frameless glass shower. Additional bedrooms are thoughtfully arranged, including a secondary en-suite bedroom and a well-appointed hall bath serving the remaining rooms. The lower level provides exceptional flexibility with a large recreation room, a den with walk-in closet, a full bath, and dedicated storage and utility spaces, accommodating guests, hobbies, fitness, or work-from-home needs. Outside, mature landscaping, flagstone walkways, and a brick patio create inviting outdoor gathering spaces, while the expansive lot offers a sense of privacy rarely found this close to major amenities. Ideally positioned just minutes from Tysons Corner, Tysons Galleria, Capital One Center, Metro access, major commuter routes, and the shops and restaurants of downtown McLean, the home offers the convenience of urban accessibility without sacrificing space, privacy, or tranquility. Combining energy-conscious living, substantial recent capital improvements, a generous homesite, and a premier McLean location, 1077 Spring Hill Road presents an opportunity to enjoy a lifestyle that is both connected and remarkably self-sufficient.
