6311 Carnegie Drive offers far more than its street presence suggests. This split-level mid-century modern home has undergone a complete, thoughtful transformation while preserving the architectural character that makes the style so appealing. The result is over 3,600 square feet across three fully finished levels, with a layout that feels open, flexible, and incredibly livable.

Virtually every major system is brand new. Updates include a new roof, HardiePlank siding, gutters, Andersen windows, two new HVAC systems, all new plumbing and water heater, upgraded insulation exceeding industry standards, a new 400-amp electrical service with all new wiring, and abundant recessed lighting on dimmers. Strategically placed outlets include USB chargers, and exterior outlets are installed to accommodate wireless cameras and motion-activated lighting. The home truly lives like new construction, but with a level of finish and attention to detail that is rarely found in new builds.

The upper level features four bedrooms, three full bathrooms, and a dedicated laundry room. The primary suite is a standout, with vaulted ceilings highlighted by wood beam detailing and a spa-inspired bath featuring a soaking tub, separate shower with three body jets, heated floors, and refined finishes throughout.

The main level is designed for both everyday living and entertaining, anchored by an open-concept kitchen, dining area, and family room filled with natural light from four skylights. A newly added den or office sits just off the main living space, complete with a pocket door and direct access to the deck. A functional mudroom connects to the single-car garage, creating an ideal drop zone for daily life. The kitchen is outfitted with top-of-the-line, German-made cabinetry, two islands, and professional appliances, including a 36-inch, six-burner Wolf gas range with pot filler.

The lower level offers exceptional flexibility with two additional bedrooms and a full bath, or the option for an office, bedroom, exercise room, and bath. Two separate recreation rooms and direct walk-out access to a stone patio complete the space.

Outside, the property still offers a generous, fenced backyard--an increasingly rare feature that complements the home's expanded interior living. The owner is a registered new home builder and will provide the buyer with the same warranty offered for new construction in Montgomery County. This is a rare opportunity to enjoy modern comfort, quality craftsmanship, and mid-century character in a truly move-in-ready home.
