About This Home

As of April 2026

Set on 36 pristine acres of Colorado landscape, 20 min above Boulder, this exceptional horse property exudes timeless elegance & unmatched serenity, w/ sweeping views toward Gross Reservoir, James Peak, & Eldorado Canyon. Crafted in 1996 by esteemed builder Scott Turnipseed in his inaugural design/build, this architectural masterpiece evokes a Jackson Hole lodge, blending rustic charm & modern sophistication. The main level features 12-ft ceilings, wide-plank pine floors, & an open layout with a guest bedroom, kitchen, dining, & living areas-all anchored by a stately wood-burning fireplace. Expansive west facing windows flood the space with natural light & frame a 14-acre meadow-an equestrian dream with County-approved sites for an arena, barns & outbuildings. Upstairs, the primary suite offers a peaceful retreat with meadow views, a sitting area, a 5-piece bath, & a spacious walk-in closet, plus a flexible 2nd bedroom or office. The unfinished, daylit basement includes rough-in plumbing for a full bath with expansion potential. A wrap-around deck invites seamless indoor-outdoor living, while a hot tub promises quiet evenings beneath the stars. Surrounded by aspens, dramatic rock croppings, & diverse terrain, the property abounds in natural beauty & privacy. Bordering Boulder County Open Space at Myers Gulch & near Walker Ranch, it offers immediate access to hiking, biking, horseback riding, & fly fishing along South Boulder Creek. Nearby Gross Reservoir provides opportunities for camping, paddleboarding, & non-motorized boating, while Eldora Ski Area is a mere 30 min away. Water is secure with a deep well tapping the Eldorado Springs aquifer & a 500-gal cistern. A run-in shed & fenced paddock are ready for horses, & wildlife flourishes in the protected meadow. A strong community, a nearby fire station, & a local deputy-brings added peace of mind. This rare gem offers limitless potential for those seeking beauty, privacy, or the ultimate equestrian escape.
