Now repositioned for the spring market, this is a rare opportunity to secure the only new construction residence currently available in Lyon Village. Welcome home to 3108 Key Boulevard, a newly constructed residence ideally located in the heart of Lyon Village. Set on a picturesque, evenly proportioned lot, this thoughtfully designed home offers approximately 6,010 square feet of refined living space across four finished levels, combining privacy, scale, and exceptional walkability to parks, Metro, schools, trails, and neighborhood dining. The home features a well-conceived floor plan that balances openness with everyday livability. At its center is a gourmet chef’s kitchen appointed with custom inset cabinetry, a 48” Wolf gas range, Sub-Zero refrigeration, Cove dishwasher, and an oversized island offering abundant storage and prep space. The adjacent family room opens seamlessly to a screened porch with gas fireplace, leading to a stone patio and private rear yard, well suited for entertaining and outdoor dining. The primary suite offers a private retreat with a sitting area, dual walk-in closets, and a spa-inspired bath. Secondary bedrooms are generously sized and include en suite baths. The third-level loft provides flexible living space with an additional bath and a covered porch showcasing skyline views. The light-filled lower level includes a spacious recreation room with wet bar, fitness room, and a guest or au pair suite with walk-up access to the rear yard. Additional highlights include Marvin windows throughout, spray-foam insulation with Rockwool sound separation, 10-foot ceilings on the main level, 9-foot ceilings on upper and lower levels, elevator-ready construction, an attached garage, and an oversized paver driveway providing ample off-street parking. Thoughtfully designed and meticulously crafted by Rock Spring Homes, a local boutique builder with decades of experience delivering high-quality new construction throughout Arlington, this residence offers a compelling combination of location, design, and build quality in one of the area’s most sought-after neighborhoods.
