Tucked away on three private acres, 4719 Old Mill Bottom Road offers the kind of space, flexibility, and peaceful setting that is becoming increasingly difficult to find in Mount Airy. Fully renovated from top to bottom, this three-bedroom, three-full-bath home combines modern updates with the freedom of country living—without feeling remote or disconnected. Inside, the renovation feels clean, intentional, and move-in ready. The brand-new kitchen serves as the centerpiece of the home, with updated finishes, modern cabinetry, and plenty of room for everyday meals, entertaining, and gathering. New mini-split systems provide efficient, customizable heating and cooling throughout the home, while the new roof offers added peace of mind for years to come. Each of the three full bathrooms has been updated, giving every level of the home a polished and cohesive feel. The finished basement adds an entirely separate dimension to the property. With its own private exterior entrance, full bathroom, and independent living space, it functions as an ADU-style suite that could be ideal for extended family, long-term guests, a private home office, or a separate rental opportunity. It provides privacy and separation while still remaining connected to the main home—an arrangement that is difficult to replicate in a traditional floor plan. Outside, the property opens up across approximately three acres, providing room to spread out, entertain, garden, store equipment, or simply enjoy the quiet surroundings. The detached pole barn offers even more flexibility and could easily serve as a garage, workshop, equipment building, hobby space, or additional storage. Whether you need space for vehicles, tools, recreational equipment, or future projects, this property gives you options. Private, fully updated, and designed to accommodate more than just a standard living arrangement, 4719 Old Mill Bottom Road is a home that can adapt to the way you live.
