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.

    "I used to live here for about 5 years, and it's where I bought my first home. Niwot has a compact downtown and adjacent shopping area, with an interesting blend of breakfast, lunch, and dinner restaurants within a few hundred yards of each other. The Cottonwood park west subdivision is adjacent to both areas, with a walking path to both. The homes are small, as are the lots, but laid out with privacy in mind. Most homes have direct access (back gate)to a well kept, pet friendly park, with Volleyball, basketball, and playground equipment for younger kids. Niwot schools are rated at the very top of the charts, and I selected my second home on criteria that they remain in the Niwot school district. Due to the smaller house sizes, you will find a mix of many first time homeowners,(singles and couples) and retirees, who have downsized and like the quiet country atmosphere, yet with highly walkability."

    "I moved to Niwot in 1989. It has grown since then but it has a limited amount of land to build on so there are only a few lots left. The sense of community is strong. Schools are excellent. Great location midway between Longmont and Boulder and only 45 miles from Denver and DIA make it very popular. Cute little downtown with lots of restaurants and community activities make it a fun place to live."
