1. Property Overview


The Lyon Estate represents the rarest of opportunities: a 137-acre presidential-grade compound in Orange County’s most exclusive gated community, Coto de Caza. This is not just a home; it is a self-contained world of luxury, privacy, and capability.


2. Historical Significance


Built by Major General William Lyon, this estate has hosted presidents, including Ronald Reagan, and served as a gathering place for political and business leaders. Its provenance adds an intangible value that few properties can claim.


3. Architectural Features


The main residence is a Georgian Colonial masterpiece, offering over 47,000 square feet of refined living space. From the grand double staircase to the hand-milled woodwork, every detail speaks of uncompromising quality.


4. Amenities & Facilities



  • Car Museum: A 23,679 sqft facility with turntables and shop.

  • Equestrian Center: 10-stall barn and championship arena.

  • Recreation: Resort pool, tennis courts, and manicured gardens.


5. Development Potential


Uniquely, this estate comes with approved entitlements for a 25-lot luxury enclave. This allows a buyer to either preserve the estate in its entirety or realize over $200M in development value.


6. Financial Analysis


At a listing price of $125M, the price per acre and replacement cost analysis suggests significant intrinsic value, particularly when factoring in the development upside.
