The Castle is a multi-level, twenty-seven room 12,000 square foot home with eight foot thick walls, a Great Hall with a sixteen foot ceiling, a swing porch, pantry, four fireplaces, a dutch oven, dumb waiter, complete intercom system and a gasoline-engine-assisted windmill. The windmill pumped water from the springs to redwood storage tanks and the room under the windmill was used to cool meats and vegetables.
The finished exterior, the stone work, windmill, bricks and tiles, and arches reflect French, Dutch, Spanish, and Medieval styles. Roof tiles are supported on a concrete roof sustained by rock buttresses. Eaves are troughs hewn from unfinished eucalyptus trunks supported by gargoyle figures. Aztec, Greek, Roman, North American, and Oriental crafts, decorated the exterior and interior of the house. All were tributes to prosperity, health, friendship, and good luck. Other motifs were taken from Persian, Arabic and Oriental rug designs used in the house.
