    What's special

    Private botanical sanctuaryExpansive picture windowsSix-acre retreat
    MLS# 293518 There are homes that check boxes, and then there are properties that tell a story.At the end of a quiet country lane, where the sounds of the city fade into birdsong and the horizon stretches for miles, sits a remarkable six-acre retreat that feels worlds away—yet remains just minutes from shopping, dining, schools, and everyday conveniences.Originally custom built by renowned local builder Lapierre in 1984, this one-of-a-kind property was thoughtfully designed to embrace its surroundings. Every window seems to frame inspiration from rolling hills and wooded settings to sunrises that greet you early and sunsets that linger long after the day is done.Stroll through mature gardens bursting with color and character. Pick fruit from established trees like apples, apricots, pears and cherries. Wander among grapevines, the berry bushes, the towering shade trees, and even living Christmas trees planted and nurtured through the decades. The result is a landscape that feels less like a yard and more like a private botanical sanctuary.Inside, the 2,550-square-foot home offers warmth, comfort, and spaces designed for gathering. The heart of the home may very well be the spectacular family room and library addition completed in 2005. Wrapped in expansive picture windows, this inviting space draws the outdoors in, offering breathtaking views in every season. Whether you're curled up beside the fireplace with a favorite book, entertaining friends, or simply enjoying a quiet morning coffee, the room serves as a daily reminder of why this property is so special. The home features three bedrooms and two-and-a-half baths, blending timeless craftsmanship with the charm and character that only a custom home can provide.Outside, the possibilities are endless. A spacious 1,200-square-foot shop provides room for hobbies, projects, equipment, or storage. A greenhouse extends the growing season, while the chicken coop offers the opportunity for a sustainable country lifestyle. Horse and hiking trails nearby invite exploration and adventure right from your doorstep.This is a place where evenings are spent watching the changing colors of the landscape, where life can flourish, where memories are made around the fireplace, and where every season brings you home. More than a home, this is a legacy property—a place to slow down, breathe deeply, and enjoy the life you've always imagined.
