Perched high in the Ventura foothills on an exceptionally private estate lot, this one-of-a-kind residence commands breathtaking 280-degree panoramic views spanning the Pacific Ocean, coastline, harbor, pier, mountains, and city lights. Awe-inspiring ocean vistas can be enjoyed from nearly every room, the wrap-around decks & the fourth-story tower which is a true architectural showpiece. 440 Mariposa was designed & built in 1999 by the owner, Frank Peterson, in a Frank Lloyd Wright style known as Organic Architecture, that harmonizes structure with the natural environment.Its hexagonal design, handcrafted woodwork, and flowing, interconnected rooms centered around a massive, central fireplace are key elements of Wright's architectural style. Being environmentally conscious, Peterson installed a copper roof that was ingeniously engineered to channel rainwater into an underground well. Some of the many creative touches include a custom marble floor embedded with pebbles in the shape of a stream, a wrought iron railing depicting various sea animals, a handcrafted stained-glass entry, and a garage door embellished with a hand carved frieze.Both the lower level & the west wing are self-contained guest units with kitchenettes, full baths & private entrances. A truly unforgettable residence that is designed to inspire, impress, and endure.
