About This Home

As of July 2024

Tucked behind the Boulder Flatirons this fully remodeled gem sits on 37+ acres surrounded by miles and miles of protected land that can never be developed or built on. If privacy, peace, and views - all with easy access to Boulder - is what you are looking for, 428 Bison is home. The studs-out remodel includes a high-end kitchen featuring Thermador appliances, radiant heat under the two new ensuite bathrooms and under the white oak floors on the main level. Luxe wool berber carpet upstairs. New windows, new electric and plumbing. This energy efficient home has a HERS rating of 61, a newer metal roof, and the composite exterior was recently painted. Outside the house you'll find new decking, new flagstone flatwork, newly rebuilt moss rock retaining walls, and professional landscaping. The 37 acres includes two historic barns from the original Walker Ranch and your own seasonal creek with private patio (on the creek), the ideal place to unwind and recharge in complete privacy. You can walk out your door and onto the Ethel Harrold trailhead that abuts the western edge of the property, or take a leisurely walk up the private road to the secret back entrance to Bear Mountain.
