This estate seamlessly blends bold, clean lines with the natural grandeur of Boulder's Front Range legendary landscape. Framed by floor-to-ceiling glass, the panoramic views are nothing short of breathtaking-from the iconic sandstone towers of the Flatirons rising in sculptural splendor to the shimmering skyline of Denver stretching across the horizon. Every sunrise casts a golden glow across the valleys below, while city lights twinkle in the distance each evening like a sea of stars.The open-concept interior flows effortlessly between expansive living, dining, and entertaining spaces, anchored by a state-of-the-art chef's kitchen, a dramatic great room with soaring ceilings with exposed steel beams, and a roaring fireplace that merges indoor elegance with outdoor serenity, all with a Net Zero energy performance. Multiple decks and terraces invite you to breathe in the crisp mountain air, entertain beneath the alpenglow, or simply watch hawks glide on thermals over the foothills. Retreat to a primary suite designed as a personal sanctuary, complete with a spa-inspired bath, custom dressing room, and private terrace perched high above native and natural landscape of the property. Three additional ensuite bedrooms ensures there's space for every guest. Located just minutes from downtown Boulder's renowned shops, restaurants, and trailheads, this is where modern luxury meets wild beauty. Whether as a full-time residence or a seasonal escape, this home is a rare opportunity to own a piece of Colorado's most iconic terrain, with the Rocky Mountains your feet.
