Welcome to a truly one-of-a-kind property, inside and out. Upon entrance through the gate, a tree-lined drive sets the tone—its canopy lush and vibrant in both summer and fall. The circular driveway makes the arrival all the more elegant. As you approach, you’ll also notice the fantastic mountain vistas and serenity this property offers. Sitting on just over five acres, this custom-built home, designed by renowned architect Kyle Callahan, is truly elegant, with an emphasis on nature. Expansive windows throughout flood the home with rich, golden light and offer magnificent views of the meadow and mountains—you may never want to leave.
The heart of the home is a gourmet kitchen, which overlooks the spacious living room featuring soaring ceilings and a picture window. The main-floor primary is a true retreat, featuring a luxurious, spa-like bath and amazing views. For convenience and privacy, each bedroom has its own bathroom as well. Additional features include two office spaces, a large sunroom, a mother-in-law suite, and a heated/cooled studio above the detached garage. There are heated floors and five fireplaces for extra winter comfort inside, while a built-in grill makes summer entertaining seamless, both indoors and out. You'll also find an attached 2-car garage, a detached 2-car garage, and a 2,100+ square foot barn—perfect for horses or extra storage.
Located in the gated and private Caribou Springs Ranch community, you'll enjoy exclusive amenities such as a pool, spa, tennis court, a community stable for boarding your horse(s) and over five miles of multi-purpose trails to explore. Boulder and Lyons are also less than 20 minutes away for shopping and dining. This is a dream property and a one-of-a-kind opportunity to own a piece of Colorado.
