This stunning residence features 4 spacious bedrooms, 3.5 bathrooms, a fully finished basement, and a detached 2-car garage designed for both everyday living and high-end functionality. In addition to the bedrooms, the home also includes a private ground-level office that can easily be converted into a 5th bedroom, guest suite, or flexible living space.

Additional upgrades include a fully automatic whole-house Generac natural gas generator, 200-amp electric service with multiple subpanels, FiOS prewiring, Cat5/Cat6 networking, and a conditioned attic with future-ready electrical circuits. The fully finished basement adds tremendous additional living and entertaining space. Step outside to your beautifully manicured private backyard oasis featuring a large patio, propane fire pit, underground-powered landscape lighting, and an in-ground sprinkler system. The home is also equipped with soffit and peak outlets specifically designed for seamless holiday lighting displays, allowing for clean, extension-cord-free decorating with dedicated switch controls throughout the exterior. A rare feature for the area, the property offers two separate driveways along with a detached 2-car garage featuring 14-foot ceilings, tiled floors, drywall finish, mini-split heating and cooling, 240-amp service, and built-in compressed air lines — ideal for car enthusiasts, hobbyists, or workshop use.
