26904 Mesa Grande, Santa Ysabel Property Listing: MLS® #250040180

The property shimmers under the mountain sun, setting the stage for a life of privacy, recreation, and timeless California living. Completed in 2018 by master builder Greg Agee and architect John Jensen, the main residence is a showcase of design and craftsmanship. At approx. 6,500 sq. ft., soaring 20-foot ceilings, six bedrooms, five bathrooms, a media room, custom lighting and storage, and a three-car garage, the home captures sweeping views of the Santa Ysabel Mountains. Light-filled interiors blend seamlessly with the outdoors, while a resort-style pool and spa, spanning 55 feet, solar-heated with an automatic cover, invites year-round relaxation. Multiple fireplaces and firepits create the perfect backdrop for gatherings large and small. Beyond the residence, the property transforms into an extraordinary retreat for recreation and entertaining. A full-size pickleball court, cowboy croquet, organic garden, and chicken coop bring both playfulness and practicality. The one-of-a-kind “Miner’s Village” along the creek—complete with stage—offers a magical setting for live music, performances, or private celebrations. Guests can fish or kayak at Blackberry Pond, which is approximately .5 acres at a 20 foot depth at its fullest, or head to the shooting range, outfitted with multiple..
