Welcome to 4676 Concession 11, Puslinch-a once-in-a-lifetime opportunity to own an extraordinary 100-acre country estate offering ultimate privacy and convenience. Tucked away on a quiet sideroad with a winding paved driveway, this peaceful sanctuary is just 10 minutes from Highway 401 and minutes from South Guelph's shopping and dining. This impressive 2,573 sq ft ranch-style home features soaring vaulted ceilings, expansive windows, multiple skylights, and a spectacular 40-foot living and dining room built for entertaining with multi-season views. The main floor boasts 3 bedrooms and 2 bathrooms, while the full-height walkout basement features a massive 4th bedroom and full bathroom, offering ideal flexibility for multi-generational living or a guest suite. Outdoor enthusiasts and nature lovers will thrive with approximately 10 kilometres of groomed private trails across nearly 92 acres of mixed forest, open meadows, and wetlands with a custom boardwalk. Perfect for cross-country skiing, ATVs, dirt biking, hiking, and snowshoeing, the private trail network is adjacent to neighbouring Grand River Conservation Authority (GRCA) lands. The property is a birdwatcher's paradise with over 40 species alongside deer, foxes, and wild turkeys. Exceptional infrastructure includes a massive 80'x40' workshop complex. A 30'x40' portion of the shop is fully insulated, heated, and equipped with plumbing, woodworking, and metalworking stations-perfect for trades or a home business-while the remaining section handles heavy equipment and farm machinery. Additional highlights include a 1,200 sq ft entertainment deck with a pergola, parking for over 20 vehicles, a pond, a woodshed, fibre optic internet, a newer roof, updated flooring, and fresh interior paint. Backed by favourable preliminary assessments, this acreage is also a candidate for future land severance. View additional details and features at 4676concession11.ca.
