One-of-a-Kind Luxury Estate in Gated Signal Hill. Welcome to this extraordinary custom residence, set on a private one-acre lot in the prestigious gated community of Signal Hill. Originally built in 1999, & has been completely reimagined with a full-scale renovation, every surface touched, every finish elevated to the highest standard. The home feels brand new yet stands on solid architectural bones. Pool featuring swim-up bar stools, surrounded by lush landscaping. A new slab has been poured beneath the pool deck, fully plumbed and ready for your outdoor kitchen vision. There's also a newly constructed dog washing station for your four-legged family members. The expansive lower level offers fully customizable space, with 4,931 square feet (see attached County Assessor/Court House document) & 15' ceilings, a blank canvas for your dreams. Imagine a car collector's showroom (room for 15+ vehicles), golf simulator, bowling alley, indoor shooting range, rock climbing wall, home theater, music studio, spa retreat, or even a private art gallery. The space is also ideal for a gym, CrossFit studio, dance/yoga space, or a sports bar-style lounge with pool tables and big screens. Three (3) 10' commercial-grade garage bay doors and a separate driveway complete the picture. You must tour this rare gem in person to fully appreciate the unmatched craftsmanship and limitless potential.
