21025 Running Horse Road

Discreetly set at the end of a private road, on the southern flank of Round Mountain, The Treehouse is a captivating architectural gem, embracing the relationship between nature & design. Encompassing four acres of gently sloping forest, the property greets you w/ a landscape of ancient boulders, curated walking trails & a verdant canopy of oak, cedar & pine. Built using innovative, outside-the-box practices, this residence stands as an example of inspired architecture, intentionally designed to honor its secluded environment. Inside, dramatic floor-to-ceiling glass walls frame wide views over a rugged, wooded ravine, offering a sense of floating among the treetops. The interior has been thoughtfully modernized in recent years, blending high-end contemporary upgrades w/ the home's original organic heritage. The main level serves as its heart, centered around a striking open staircase. Here, you will find a remodeled chef's kitchen, updated half bath, bright dining area & cozy living room anchored by a classic wood-burning stove for cool mountain evenings. The attached workshop provides generous space for storage & laundry plus a fully-equipped home gym. Upstairs, the home offers 3 bedrooms and 2 bathrooms, organized in a highly flexible layout. A standout feature is the integrated in-law suite, complete with its own kitchenette & elevated deck. This functional space serves as a cozy guest retreat or can be closed off to allow for multi-generational living or potential rental income. All bathrooms have been meticulously remodeled using rustic, industrial fixtures & premium Cle tile, w/ the primary bath also featuring a deep jetted tub. At the head of the stairs, a unique lofted space provides an ideal footprint for a quiet home office, hobby studio, or meditation room. The indoor/outdoor connection continues w/ expansive cedar decks wrapping the home, offering private spaces to lounge, dine alfresco, or bathe in the Japanese-style soaking tub. For those drawn to sustainable living, the property includes a fully fenced homesteading garden complete w/ mature fruit trees, greenhouse, active beehive & chicken coop. An extra-deep well, 3000 gal storage tanks, Starlink connectivity, Generac backup generator & EV charger top off the list of features. The home is being sold fully furnished for a truly turn-key opportunity. Twelve minutes from Nevada City and 10 minutes to the Yuba River - secluded yet deeply sophisticated - this property is a true modern paradise.
