Experience one of Boulder's most coveted locations, where modern architecture, sophisticated design, and an irreplaceable setting come together at the base of the iconic Flatirons. Just blocks from Chautauqua Park and Boulder's legendary trail system, this exceptional home offers immediate access to some of the city's finest hiking, open space, and outdoor recreation, while remaining just minutes from the vibrant shops, restaurants, and culture of downtown Boulder. Perfectly positioned on a corner lot surrounded by trees, the home captures breathtaking Flatiron and mountain views from every level. Thoughtfully designed to create a seamless connection between indoor and outdoor living, every space feels light-filled, welcoming, and effortlessly elegant. The expansive living and dining room is anchored by a stunning floor-to-ceiling stone fireplace, creating a warm and inviting gathering space.

Upstairs, every bedroom enjoys spectacular Flatiron views, while the luxurious primary suite serves as a private retreat complete with a beautifully appointed five-piece spa bath and refined finishes throughout. The finished walk-out lower level is bright and inviting, offering flexibility as a guest suite, multigenerational living space, or potential ADU. Outdoors, the private backyard is a peaceful, professionally landscaped oasis designed for relaxation and entertaining. In front, the thoughtfully xeriscaped yard features a fire pit where you can gather with friends while taking in the mountain views. This is a rare opportunity to own a meticulously maintained home in one of Boulder's most extraordinary settings. Offering an unmatched combination of exceptional design, breathtaking scenery, and an iconic location, this home embodies the very best of the Boulder lifestyle.
