Welcome home to 4541 W. Westchester Lane, a beautifully maintained retreat in Libertyville's sought-after Lancaster subdivision, lovingly cared for by the same family for over 26 years. From the moment you step inside, gorgeous marble floors welcome you into the home, the warm engineered wood floors flow through the bedrooms and hallways. With four spacious bedrooms and four and a half baths, there's room for everyone to spread out and settle in. A dedicated office offers a quiet sanctuary to work from home, and upgraded walk-in closets, along with a private office off the primary bedroom, bring everyday living a little extra ease. Downstairs, the fully finished basement adds more living space with a full bathroom of its own - perfect for guests, movie nights, or a home gym. Step outside to your own backyard oasis, where a 30-foot in-ground pool with heater and automatic cover invites summer afternoons and evenings by the water. Major updates offer real peace of mind, including a roof and windows replaced three years ago, new window blinds, a 24 KVA standby generator, leaf filter gutter protection, and solar panels for added efficiency. With 3,864 square feet of agla, and 984 square feet of basement, this is a home where comfort, care, and thoughtful updates come together, ready for its next chapter.
