Description
Tucked away at the end of a quiet cul-de-sac—shared with just one other home—this 1.36-acre Niwot estate offers rare privacy, space, and serenity. Surrounded by over 120 mature trees, the property feels like a secluded retreat while still being close to everything.
Offered for the first time in 25+ years, this home has been meticulously maintained and thoughtfully designed for both everyday living and entertaining.
Inside, the main level features a functional, flowing layout with three fireplaces anchoring the family room, formal living room, and main-floor primary suite. The spacious kitchen opens to the main living areas and includes a cozy eat-in nook, while a formal dining room provides space for gatherings and special occasions. A dedicated office with an attached half bath adds flexibility.
Step out onto the covered walk-out deck and take in the beautifully designed backyard, an extension of the home’s living space.
Upstairs, each of the three bedrooms includes its own en-suite bathroom, offering comfort and privacy. The walkout basement provides an open entertaining area, ¾ bath, workshop, storage, and direct access to the backyard.
Outside, the property transforms into a private resort with a pool & built in hot tub, putting green, tiki bar, multiple patios, and expansive lawn space perfect for entertaining or relaxing in total privacy.
Additional highlights include a three-car garage, multiple outdoor living spaces, and exceptional care throughout.
A rare opportunity to own a private, resort-style property in one of Niwot's most desirable settings.

3/10GreatSchools RatingParent Rating AverageMy kid goes here and he hates it there is a teacher named Jennifer macios that picks on him he comes home and complains about her. She will get him in trouble for talking when it wasn't even him talking and it was th kids around him. She also complained about property damage because he found a balloon in her room and kicked him out for that. If I were the principal here I would fire her immediately.Parent Review1mo ago - Niwot Elementary School

9/10GreatSchools RatingParent Rating AverageWe have two children at Niwot Elementary and couldn’t be more grateful for the experience. After moving from a nearby district, we were amazed by the level of support our family received—something we hadn’t experienced before. Our kids have both made tremendous growth academically and socially since enrolling.The school community is incredibly strong, and the PTA works tirelessly to create meaningful events for families while also raising funds that directly support students, including funding additional paraprofessional staff in classrooms.The front office staff is kind and welcoming, the teachers are talented and deeply invested in their students, and the principal sets a positive, inclusive tone that’s felt throughout the school. We truly feel lucky to be part of the Niwot Elementary community.Parent Review10mo ago - Niwot High School

9/10GreatSchools RatingParent Rating AverageWas an assistant coach here and saw ignoree athletes, disrespectful parents, and arrogant faculty. Only star athletes were focused on by the head coach. I was undermined by faculty and it hamstringed my ability to coach. To top it off, they ask for me to come back ane would only pay $3000 for 4 months of full time work aka slave labor. For how funded they are, you think they could pay staff.Other Review9mo ago
