About 12357 N 75th St

Lakeside living near Boulder is virtually unheard of, making 12357 N 75th Street one of the most exceptional opportunities in the region. Set on 7 lush, irrigated acres with direct access to a private lake and sweeping views of Longs Peak and the entire Front Range, this Boulder County estate offers natural beauty, luxury, and privacy just 20 min. from downtown Boulder. At the heart of the property is a newly constructed 5,754 SF residence, thoughtfully designed for elevated indoor-outdoor living.

A dramatic open-hearth fireplace anchors the great room, where rich textures, such as handcrafted cabinetry, reclaimed wood beams, and custom steel elements, create depth and sophistication. The home features four spacious bedrooms and six bathrooms, including a luxurious primary suite with a private loft, balcony, coffee bar, double-sided steel fireplace, spa bath with a soaking tub and steam shower, and a custom-designed walk-in closet. A dining room, private home office, and generous laundry room round out the home's well-appointed interior. Step outside to a true lifestyle haven. A heated pool and spa, lakeside firepit, and expansive patios offer multiple venues for entertaining or unwinding in total privacy.
