A rare offering in Simi Valley, this custom 6-bedroom, 6.5-bath estate crowns the end of a quiet cul-de-sac, presenting over 5,600 sq. ft. of refined living on a 25,000+ sq. ft. lot. Currently owned by a Hollywood producer who sought a private retreat outside the city, the estate has also hosted gatherings attended by movie stars, directors, and producers -- a testament to its scale and entertaining appeal. The approach is framed by mature shade trees, lush landscaping, river rock accents, and a custom river rock mailbox. An extra-long and wide stamped concrete driveway with possible RV parking enhances curb appeal, while the custom double-door entry with leaded glass sidelights sets a welcoming tone. Inside, the foyer opens with real wood floors, soaring ceilings, and an artisan agate chandelier. To the left, a study/office with floor-to-ceiling custom built-ins provides the perfect setting for a home library or workspace, while still offering the versatility of a bedroom with ensuite bath. Nearby, French glass doors open to an additional room, previously used as a music room, ideal as a den, playroom, or creative space. The formal living room rises to 30 feet with abundant windows and a travertine raised-hearth fireplace, while French doors lead to the backyard. Off the living room, a dedicated theater room boasts a 210' screen, Sony projector, blackout curtains, surround sound, and 7 reclining chairs -- all included. The gourmet kitchen showcases two full-capacity Sub-Zero units--refrigerator and freezer, a Viking 6-burner cooktop with griddle and hood flanked by custom spice racks, a Viking microwave, Bosch dishwasher, abundant cabinetry with built-in storage nooks, and an extra-long granite island with travertine accents and pendant lighting. A butler's pantry with sink, wine refrigeration, and walk-in pantry enhances functionality, while a built-in china cabinet and casual dining area add charm. A second bedroom with adjacent bath, laundry room, and guest powder room complete the lower level. Upstairs, an open loft-style landing creates a striking catwalk across the home, overlooking the living areas below and connecting the bedrooms. The primary suite offers a private retreat with a balcony overlooking the backyard, sitting area, fireplace, dual walk-in closets with organizers, and a marble bath with dual vanities, soaking tub, and steam shower with dual heads. Three additional ensuite bedrooms with closet organizers complete the upper floor. The backyard feels like a private park, with expansive lawns, stamped concrete patios, covered sitting areas, koi pond with waterfall and wood bridge, rose gardens, grapevines, and fruit trees -- plus plenty of space to add a pool, greenhouse, or other features to fit your lifestyle. The spacious 3-car garage includes epoxy flooring, overhead storage, an updated electrical panel, two 220v outlets for EV charging, and a full-size safe. Energy efficiency is enhanced by a solar system paired with four Tesla wall batteries, designed to provide significant backup capability, including support for the home's zoned A/C system. Additional features include three fireplaces, dual-paned windows with shutters, Nest temperature controls in every room, a recirculating water heater, a replaced sewer line, and fiber-optic connectivity for reliable high-speed internet access. Additional highlights include no HOA, a quiet neighborhood setting, and proximity to Lemon Park. Finishing touches include all artisan chandeliers and sconces handcrafted by Corbett. Blending custom design, thoughtful upgrades, and resort-style grounds, this estate is truly one of Simi Valley's premier residences.
