    What's special

    If you’re looking for a home in Thornton that gives you actual breathing room without sacrificing convenience, this is the one! The home sits right at the end of a quiet cul-de-sac and matches up against open space and walking trails. Because of how the lot is positioned, you only have one true residential neighbor. The entire backyard feels incredibly private, completely fenced in, and features a great spacious deck. It is the exact kind of setup where you can host a barbecue with friends or drink your morning coffee. Inside, the floor plan is a multi-level layout that flows naturally. You get a formal living and dining area up front, which opens up into a central renovated kitchen and a cozy lower-level family room with a gas fireplace. Vaulted ceilings and massive windows pull in tons of natural light, making the main living spaces feel bright and open. Up the stairs, the primary suite features its own dedicated bath, alongside two additional bedrooms and a full guest bathroom. If you ever need more room to expand, the unfinished basement is basically a blank canvas for a gym, extra storage, or an entertainment space. The neighborhood amenities are just as solid. You are a quick walk or drive from the Trailwinds Recreation Center, which makes grabbing a workout or hitting the pool effortless. It’s prime location is less than ten minutes from Eagleview Elementary School, along with the Anythink Nature Library opening up right down the street. It’s a massive 15-acre indoor-outdoor campus with trails, workshops, and community spaces that is going to be a huge anchor for this part of town. It’s rare to find a home that checks the boxes for interior space, excellent schools, and a highly private lot. This one does it effortlessly!
