Completed in 2025 and set on an expansive 10,000+ square foot lot in the Castro Valley Hills, this one-of-a-kind custom-built residence offers 4,216 square feet of uncompromising luxury living with breathtaking Bay views. Soaring 10-foot ceilings, wide-plank hardwood floors, top-of-the-line appliances, and impeccably curated high-end finishes set the tone from the moment you enter. The main level features two bedroom suites — including a grand primary suite — a private office, and a half bathroom, with sweeping Bay views enjoyed from the expansive balcony. The lower level impresses equally with a second primary suite, two additional bedroom suites, a gym and storage room, a half bathroom, and a spacious family room complete with a sophisticated wet bar — perfect for entertaining or multi-generational living. Five bedroom suites, a private office, five full bathrooms, and two half bathrooms in total. A dual-zone HVAC system, solar lease for energy efficiency, and low-maintenance front and back yards round out this extraordinary offering. A rare opportunity to own a brand-new custom estate in one of the East Bay’s most desirable communities — this one truly has it all.
