Simka, a contemporary Malibu castle estate by Kris Halliday, known as God’s Architect, has been listed for $34,999,000 by Jade Mills, Beverly Hills’ leading real estate professional and Coldwell Banker Realty’s No. 1 California agent, and Zach Quittman, an agent affiliated with the Beverly Hills office of Coldwell Banker Realty. Both fortress and refuge, Simka was deliberately sited and constructed with extraordinary foresight, designed to withstand fire, seismic activity, tsunami, mudslide and coastal erosion, reflecting a singular commitment to longevity, resilience and architectural integrity. Located at 11824 Ellice in Malibu, Calif, the approximately 30,000-square-foot architectural marvel has 10 bedrooms and 20 bathrooms.
“When I designed and built Simka, I wasn’t trying to match what exists on the Malibu coast. I wanted to create something that would still stand a thousand years from now, the way ancient European fortresses still rise above their landscapes today,” said Halliday. “I created it. Every detail, every angle, every structural decision, every piece of the vision came from one mind. There was no team of architects, no army of designers. It was me, my hands, my ideas and my obsession with building something that would outlive all of us.”
Constructed with more than 7,300 cubic yards of super-reinforced concrete, Simka is a singular architectural statement shaped by one vision and one guiding hand. Its commanding lines of concrete and glass are balanced by sculptural landscaping and rare natural stone sourced from around the world, embodying Halliday’s concept of “Brutality Vitality,” where strength and serenity coexist in refined harmony. Concrete is elevated from raw material to an almost tactile softness, lending the home a sense of calm power. Arrival is intentionally ceremonial, unfolding through a secondary gated entrance into a serene Zen courtyard and stone-lined pathway. Inside, floor-to-ceiling walls of glass dissolve the boundary between interior and horizon, framing uninterrupted ocean views. The home is conceived as a sanctuary, a place designed to protect, restore and inspire. Floating above the ocean, the nearly 1,800-square-foot primary suite is a deeply private retreat with its own hot tubs, fireplace lounge and spa-inspired bathroom. Additional suites mirror this sense of intimacy, combining organic materials, curated furnishings and sweeping ocean panoramas. Even the marble-clad powder rooms are conceived as sculptural works of art, underscoring the estate’s uncompromising attention to detail.
“Simka is a residence conceived with permanence at its core,” said Mills. “Rising from the bluffs above the Pacific Ocean, this awe-inspiring architectural work boasts meticulously engineered living space with a rare balance of monumentality and warmth. It is not a home created for a decade or a generation, but for centuries. Simka stands as a timeless expression of architecture, conceived for eternity.”
Life at Simka is defined by a series of immersive experiences. A 176-foot, multi-level, vein-matched stone pool features a swim-up bar, sunken lounge and dramatic viewing window that visually merges with the Pacific beyond. Rivaling the world’s finest private cinemas, the modern screening room offers a 235-inch LED screen, Dolby Atmos sound and bespoke Italian leather seating. A tranquil Japanese tea room provides a rare space for reflection and stillness. Entertaining is effortlessly supported by a full commercial-grade kitchen capable of serving up to 200 guests, alongside expansive terraces, shaded loggias and a fully equipped outdoor kitchen. Throughout the grounds, water and nature are seamlessly integrated through Japanese gardens, koi ponds, waterfalls, meditation courts and meandering pathways. Social spaces also include swinging daybeds, a circular fire lounge and open-air courtyards. Wellness is central to the estate’s design, with a private spa offering a cold plunge, sauna, treatment rooms and a fitness center accented by underwater pool windows. A private nightclub, guest suites and an underground garage accommodating up to ten vehicles complete the lifestyle amenities.
“I wanted the inside of the home to feel like a sanctuary carved from the same intention as the concrete structure itself: timeless, grounded and deeply human,” said Halliday. “The spaces are minimalist but warm, using natural textures, soft lighting and precise geometry to create a sense of calm that contrasts the power of the exterior. Every line, material and proportion are deliberate. The rooms flow like a story: open expanses that breathe, intimate corners that hold you, and long sightlines that frame the ocean as living art. Nothing is decorative for the sake of decoration; every element serves the experience of being present.”
Born and raised in the Australian outback, Halliday was working alongside his father at age thirteen, learning the grit of construction before even finishing school. At fifteen, he left the classroom for a furniture-making apprenticeship where he learned patience, precision and the beauty of craft. Not formally trained in architecture, he has held building licenses in Australia, the U.K. and Canada and has designed, developed and constructed homes that stand as both sanctuaries and fortresses. He taught himself architecture not through textbooks, but through decades of hands-on creation. Drawing inspiration from castles, temples and ancient structures that still stand, his philosophy is to create works that last centuries, not decades.
“My mission is to create not just homes, but legacies: timeless masterpieces that will stand long after we are gone,” said Halliday.
