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.
