Welcome to this thoughtfully updated 3-bedroom, 2-bath home in a prime South Burlington location. Set on a quiet street yet minutes to schools, parks, shopping, and I-89, 23 Duval Street offers comfort, efficiency, and modern convenience in one inviting package. The bright main level centers around a warm and welcoming living room featuring a beautiful gas fireplace with stone surround, a substantial wood mantel and hearth, framed by classic paneled walls and custom built-ins that add both character and functional storage. Large updated windows and doors fill the space with natural light, creating an ideal setting for relaxing or entertaining. The refreshed kitchen offers an efficient layout and includes a modern induction range, while the home's extensive energy upgrades provide peace of mind and long-term savings. Major improvements include a high-efficiency furnace and central A/C (approx. 4 years), heat-pump water heater, upgraded 200-amp electrical service, and a newer roof (approx. 7 years). A rare and highly desirable SPAN smart electric panel allows live monitoring of all circuits, remote breaker control, and detailed energy reporting. Additional smart features include a remote water shutoff and a programmable recirculating pump for near-instant hot water. The finished lower level expands the living space with a comfortable family room and a stylish wet bar with new sink-perfect for gatherings or movie nights. Washer, dryer, and a chest freezer (which doubles as a keezer for the bar taps) are included. Outside, enjoy a fully fenced backyard with a 6' eastern white cedar privacy fence offering durability with virtually no maintenance, along with a screened-in porch that provides a peaceful, bug-free space to relax and enjoy Vermont's seasons. Hard-wired for a Level-2 EV charger and ready for future expansion, this home blends smart technology, efficiency, and timeless charm in a truly move-in-ready package.
