A DISTINCTIVE AGRICULTURAL ESTATE WITH ARCHITECTURAL CHARACTER, PURPOSEFUL DESIGN & EXCEPTIONAL WATER RESOURCES. The Bauer Estate is a rare Central Valley property where architecture, agricultural planning, and thoughtful land stewardship come together on approximately 12.07 acres. Now offered at $2,950,000, this extraordinary Escalon ranch represents an opportunity to acquire not simply a residence, but a carefully developed estate designed around living, research, production, and the land itself. The approximately 7000 sq ft ranch-style residence reflects a sophisticated blend of rustic character and custom craftsmanship. Architectural elements include brick, stone, wood, glass, and metal, complemented by substantial timber detailing, custom millwork, distinctive doors, and thoughtfully designed gathering spaces. A spectacular custom atrium gallery/sunroom creates a signature architectural experience, featuring an open-beam vaulted ceiling, 16 substantial 4x6 beams, and bronze Milgard skylights that bring natural light deep into the interior. The atrium's design thoughtfully connects the indoor kitchen and outdoor entertaining areas, creating a natural relationship between the home, gardens, and surrounding acreage. Inside, the expansive floor plan offers multiple living and gathering environments, private bedroom suites, library, game/recreation areas, great room and flexible spaces suited to multigenerational living, guest accommodations, live/work arrangements or a private family compound. Custom kitchens feature substantial cabinetry, professional-grade functionality, double ovens, specialty sinks, custom fixtures, and carefully considered connections to the dining and entertaining spaces. Two fireplaces, custom flooring, and detailed architectural finishes add warmth and character throughout. Beyond the residence, the estate's true distinction is its purposeful site planning and infrastructure. Multiple structures have been strategically positioned to support agricultural research, storage, equestrian use, workshops, laboratory functions, and estate operations. Existing improvements include horse facilities, barn, greenhouse, approximately 30x60 insulated laboratory building with plumbing, HVAC, and electrical, irrigation center, pump house, energy center, utility/storage structures, shade house, and additional outbuildings. Water management is a defining component of the property's designthe estate benefits from an agricultural well and irrigation
