Single Family Home for sale in Castle Rock, CO

for $2,995,000 with 2 bedrooms and 1 full bath, 1 half bath. This 2,012 square foot home was built in 1976 on a lot size of 5.37.

A rare and remarkable offering in the prestigious Castle Pines/Happy Canyon corridor. Huge plus, this is not a part of the Castle Pines HOA, so an ADU can be built! This 5.37-acre estate property presents a once-in-a-lifetime opportunity to build your legacy. Surrounded by over 100 acres of protected open space and mature ponderosa pines, the setting is both breathtaking and private, offering unobstructed Front Range views and an unmatched sense of serenity. No HOA, lower taxes, and the ability to walk to the PGA events at the golf courses at Castle Pines elevate its appeal even further. With five level, thoughtfully placed building envelopes, the land is primed for a custom residence, equestrian barn, car collector's garage, or outdoor retreat. This is the final 5+ acre parcel available in this coveted enclave, an extraordinary chance to create something truly exceptional. Over $1M in site improvements already completed. Wildlife, views, and absolute privacy just minutes to I-25, shopping, dining, and top-tier schools. The property includes a beautifully updated 2-bedroom, 1.5-bath guest house featuring an oversized garage, expansive wrap around deck, paved drive, and elevated finishes throughout. With a private well, septic system, and natural gas already in place, the home is fully functional as-is while you design and build your forever estate.
