Welcome to 25155 Piuma Road - a one-of-a-kind architectural masterpiece by acclaimed architect Jack Moses, perched on a private promontory in the Malibu hills. Set behind gates and surrounded by a mile of open space with no neighboring homes in sight, this striking modern retreat offers unmatched privacy, tranquility, and panoramic views of the Santa Monica Mountains. Often described as a "sanctuary in the sky" or "a house in the clouds," this home is truly unlike any other and simply cannot be duplicated. Expansive walls of glass flood the interiors with natural light and frame breathtaking vistas from nearly every room. The open-concept living area features wide-plank hardwood floors, a sleek fireplace, and seamless indoor-outdoor flow to multiple terraces. The chef's kitchen is outfitted with top-of-the-line appliances, custom cabinetry, and a large island ideal for entertaining. This multi-level estate offers generously sized bedrooms, including a luxurious primary suite with spa-like amenities, a soaking tub, and jaw-dropping views. Additional features include a media room, home office, and ample guest accommodations. The outdoor spaces are nothing short of spectacular, with a resort-style infinity pool and spa, expansive decks for lounging and dining, a pergola-covered firepit lounge, and beautifully curated gardens featuring 26 fruit and citrus trees. Environmentally conscious buyers will appreciate that the home is set up to be completely off the grid, with a reverse osmosis water filtration system and a private well that pumps water from 200 feet below into two 5,000-gallon storage tanks, providing clean, free water year-round. Tucked within the Santa Monica Mountains National Recreation Area, yet just 10 minutes from both Calabasas and Nobu Malibu, 25155 Piuma Road offers the perfect blend of secluded luxury and accessible convenience. A rare opportunity to own an extraordinary retreat in the sky, where nature, design, and serenity converge.
