THE WHITE CASTLE | A RARE DIABLO LEGACY ESTATE An exceptional offering rarely seen in Diablo. Positioned on one of the community's most coveted streets near the prestigious Diablo Country Club entrance, The White Castle occupies 1.44 acres of nearly flat, park-like grounds wrapped in privacy and timeless grandeur. This extraordinary 8,190 SF estate has been thoughtfully reimagined by Jacobs & Co. and Badger Construction, blending architectural scale with highly curated design and modern livability. The predominantly single-level floor plan unfolds across two private wings, offering seven bedrooms including five en-suites and an exceptional environment for sophisticated entertaining and multigenerational living. Highlights include a dramatic expanded entry, expansive great room, formal dining, elegant bar lounge, curated wine room, prep kitchen, redesigned mud room, tech center and two laundry rooms. The primary suite has been elevated with a newly designed bath and expanded closets. Beyond the interiors, the estate delivers a true private resort experience with a pool, spa, outdoor fireplace seating, manicured grounds, new sod, substantial storage structures and a charming children's playhouse. A four-car garage caters beautifully to automotive enthusiasts. Owned solar serves both the home and pool, complemented by a whole-house generator.
