Welcome to 2477 Catherine Jean Lane, a beautifully maintained detached home perfectly positioned at the end of a quiet cul-de-sac in Mississauga's sought-after Cooksville neighbourhood. Set on a generous 54 x 115 ft lot with a nearby trail just steps from the street, the property strikes an ideal balance between peaceful, family-friendly living and the everyday convenience that makes this community so consistently appealing to discerning buyers. Approximately 4,030 square feet of living space unfolds across three well-considered levels, configured with 4+1 bedrooms and 5 bathrooms to accommodate a range of family needs with ease. The main level offers a bright and functional layout anchored by hardwood flooring, a combined living and dining area filled with natural light, and a family room centred around a beautiful stone wood-burning fireplace. A skylight-lit breakfast area with walkout access to the backyard adds an airy, connected quality to the kitchen. Upstairs, the spacious primary suite offers a private retreat with a well-appointed three-piece ensuite, while three additional bedrooms - each with generous closets and oversized windows - share a thoughtfully designed four-piece bathroom. The lower level adds meaningful versatility with a recreation room, full kitchen, dedicated laundry, an additional bedroom, a three-piece bathroom, and a flexible room suited to a home gym, office, or creative space - all accessible via a convenient private side entrance. Outdoors, the home presents with strong curb appeal: a brick interlock walkway, interlock driveway with parking for four, an attached two-car garage, and a fully fenced backyard with a built-in deck ideal for entertaining and relaxed family living. Cooksville GO Station, Square One, Trillium Health Partners, top-ranked schools, and quick access to the QEW, 403, and Hurontario Street all sit within easy reach.
