About this House

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.

    "I work in Berthod Colorado, which is a thirty minute commute. The views are stunning. So much of the great outdoors are preserved here. It’s truly magical. At the same time, there is a bus stop right next to my house that would be handy if I worked in town in Boulder. "

    "I have lived in North Boulder for 30 years- Wonderland Hills and Dakota Ridge, it has always felt safe here. My children attended Boulder Public Schools, I give the schools an A+! We live a convenient short distance to restaurants, grocery stores, schools, and shopping, ...friends hang out at our house and tell me I’m a great baker of Chocolate Chip Cookies! I love to send them home with cookies or fresh dough to bake cookies with their own families! You should bring your kids to our house on Halloween, what a treat! I walk to Pearl Street by way of Foothills Trail, through beautiful neighborhoods apple orchards, Mt. Sanitas and am fascinated by the rock formations. I bicycle many days a week and many miles, such a perfect location to start from and end up! It’s a family and friends tradition to do the Bolder Boulder on the Monday of Memorial Day weekend, so fun!
