What this listing tells us
Welcome to your private 2-acre sanctuary at 18 McCowan Lane, where peaceful country living meets everyday convenience. Set against a beautiful, scenic backdrop in Whitchurch-Stouffville, this striking modern stone bungalow introduces a grand estate lifestyle with nearly 9,000 sq. ft. of bright, beautifully designed living space. The experience begins on the sweeping circular driveway, which easily parks over 20 cars and leads to an interior that feels instantly warm and inviting. Soaring 13-foot ceilings, cathedral windows, and skylights flood the entire home with natural light, highlighting the elegant marble and rich hardwood floors. At the heart of the home is a massive open-concept kitchen with a premium granite island, flowing naturally into a glass-enclosed sunroom - the perfect spot to enjoy backyard views and gorgeous evening sunsets. The thoughtful layout is ideal for busy families and multi-generational living, featuring four spacious main-floor bedrooms (all with private ensuites), plus a huge walk-out lower level complete with versatile entertainment spaces and extra guest rooms. Step outside to your own backyard resort, where a heated in-ground pool and spa are nestled among mature trees for ultimate privacy. For car enthusiasts or hobbyists, the rare, oversized 4-car garage serves as a perfect dream workshop. Offering absolute peace of mind, the property features top-tier infrastructure including three separate heating/cooling systems, an upgraded electrical panel, and a backup generator. Best of all, this serene escape is located just minutes away from local shopping, Walmart, Canadian Tire, grocery stores, the GO Station, and Hwy 404, offering the perfect blend of luxury, privacy, and community connectivity. Welcome home.
