The 9,934 sq. ft. of living area inside this incredible 6-bedroom and 6.5-bathroom Castle creates a rare, one-of-a-kind residence. Numerous ocean-facing balconies and decks provide vistas of the Pacific Ocean, offshore Islands, beaches, mountains, city lights, canyons, farms, and much more. Spiral staircases ease movement between floors. The Main Floor features a huge living room, party area, dining room, extra-large kitchen with island, laundry area, bathrooms, fireplaces, and exterior decks. The Second Level, below the Main Level, provides for huge master bedrooms, master bathrooms, extensive storage areas, more exterior decks, and access to the Swimming pool. The Lowest Level offers several bedrooms, bathrooms, and even more potential storage areas. This lowest level will be treated as either a separate ADU or Junior ADU, depending on final approval from Ventura County. Additionally, there is a specific location for the future Elevator designed to travel between the exceptionally large Top Level Entertainment Deck down to the lowest level. There are [2] separate garages with parking space for 8 total vehicles plus extensive driveway parking that is also available. Finally, there is a very large open area located on the sloped hillside below the house for landscaping, general access, walkways, yard, playground, terraces, or a possible garden area. The estate sits behind security gates atop the Altamont Ridge HOA RE-1AC Rural Exclusive zoned land area. This huge ‘Castle on the Ridge’ was under construction until the original Owner encountered numerous personal issues and he was forced to stop. Fortunately, the original foundation and vertical components appear to have been correctly completed and constructed to code requirements, including the numerous caissons inserted into the hillside for additional structural stability. The interior was not completed before the original owner halted all work; the property largely sat empty and unfinished for many years until the current owner purchased the house. This is an incredible opportunity for someone ready to finish an incomplete construction project and turn the site into both a landmark and distinguished destination. NOTE: Property was posted with a 'Substandard Notice' on 7-8-2026, so no viewings until further notice.
