Pristine Keene Ranch estate on 4.5 acres with gently rolling landscaping that offers both privacy and usable outdoor space. This thoughtfully designed property includes a 763-square-foot detached, heated RV garage with a 14' door, sink, fully enclosed dog run, and a fully finished one-bedroom apartment above-ideal for guests, multigenerational living, or rental potential. The main home offers desirable main floor living with three bedrooms on the main level, including an updated primary suite with a cozy fireplace and private west-facing deck for sunset views. The well appointed kitchen opens to the great room and features white cabinetry, slab granite countertops, two sinks, and a center island-perfect for gatherings and daily living. Almost 2000 sq feet of outdoor decks and patios invite you to enjoy peaceful sunrises, colorful sunsets, and starlit skies. The fully finished walk-out basement includes two additional bedrooms and is built for entertaining, with a home theater (including seating and equipment), a game room, a custom wine room, and a fitness area. A whole-house Jellyfish lighting system illuminates both the main home and detached garage. Additional features include a Ring security system, a meticulously maintained yard, and a recently sealed circular asphalt driveway. The private hot tub offers a perfect place to unwind under the stars. With access to 18 miles of community horse trails and just minutes from the upcoming Dawson Trails development-featuring Costco, Trader Joe's, King Soopers and more (opening 2027)-plus the new full-movement I-25/Crystal Valley Parkway interchange underway, this home is an exceptional value in one of Castle Rock's most desirable neighborhoods.
