Property Description
The Lyon Estate is a once-in-a-generation compound spanning within Orange County's prestigious, private and gated community of Coto de Caza. Built in 1986 by US Air Force Reserve Commander and real estate magnate Major General William Lyon and his wife Willa Dean Lyon, this stately 21,000 sqft Georgian. The estate has welcomed many distinguished guests, including President Ronald Reagan and First Lady Nancy Reagan. This property commands breathtaking mountain views, balancing romantic, classical architecture with coastal California splendor. The Lyon Estate’s 3 level main residence encompasses 8 bedrooms, 11 baths and boasts meticulous design details at every turn, from its coffered wood ceilings and intricate crown moldings, to its ornate light fixtures, and walls of windows that frame gorgeous views of the grounds and views beyond. The long list of world-class features and amenities includes a private helipad, comprehensive equestrian facilities with a 10 stall barn and riding arena, a championship tennis court, a brick-clad lower-level wine cellar, and a playhouse outfitted with electricity and a TV. Three additional onsite guest houses provide ample space for hosting. One includes 2 bedrooms, 1 bath and a full kitchen, while the other 2 offer a single bedroom and a kitchenette. Manicured grounds present enchanting Italian villa-like gardens and seating areas alongside a resort-style pool, spa and a standalone pool house, which is complete with a dry sauna and dual bathrooms, each featuring changing rooms. A remarkable 23,679 sqft car museum comfortably accommodates 70 vehicles with a professional auto shop, recessed lift turntable, and wash station. Additional onsite amenities include two lakes used for irrigation, a scenic pond, a greenhouse, and comprising 4,500 Valencia and Navel Orange trees orchards, which took root more than 30 years ago. The Lyon Estate presents dual, equally exciting opportunities: Experience privacy and serenity with convenient access to Coto de Caza's members-only amenities and 2 golf courses, while enjoying proximity to Laguna Beach, Newport Coast, and the best of Orange County coastal living amidst exceptionally curated beauty and turn the page in a storied legacy. The Lyon Estate awaits its next chapter—and it's yours to write.
