Beautifully renovated luxury home in sought-after Rainbow Ridge. This exceptional residence features soaring ceilings, abundant natural light, and a thoughtfully designed layout that blends elegance with everyday functionality. After major renovations & recent upgrades, the home presents beautifully. Mature flowering trees in the rear of the home coupled with a custom pond-like water feature creates a sense of tranquility and privacy. Multiple covered outdoor patio spaces on the front and rear of the home shelter one from the elements. Raised flower beds and a dog run on the side of the home are an added bonus. Coming inside, you're greeted with a formal sitting room/office space, equipped with a gas fireplace. Turn around, and find a formal dining room, with butler's pantry, wet bar, and convenient access to the gourmet kitchen. Kitchen is fitted with state-of-the-art appliances, two islands, and plenty of cooking space. Note, the current stove is electric, but there is a gas line located just behind it. A comfortable and casual eating space is presented in the kitchen, with an equally comfortable main floor living room. Finishing out the main floor is a generously sized bedroom with its own attached bath. Going upstairs, you will find four more bedrooms -- the regal primary suite, with truly spa-like finishes, a private bedroom with en suite bath, and two more bedrooms conjoined with a jack-and-jill style bath -- fully renovated & updated, and featuring a soaking tub. Enjoy a conveniently placed laundry shoot, as well as whole-house vacuum hookups in the upper level. Moving down into the newly finished basement, find two MORE bedrooms, an updated bathroom, as well as a proper exercise/workout space & a game room. Plenty of storage is also found in the lower level. The large, 3-car attached garage comes fitted with an EV charger. This opportunity in Rainbow Ridge Estates does not come often -- strike while the iron is hot!
