Robert Downey Jr's Malibu dome house looks like Iron man's

Robert Downey Jr's Malibu estate features a bizarre futuristic dome house that looks straight out of an Iron Man movie. Known as a Binishell, the unusual concrete structure has curved walls, organic interiors and almost no straight lines. The extraordinary 6,500-square-foot Clubhouse proves the actor's real-life taste in architecture is as fascinating as Tony Stark's futuristic world.
