Rocco followed the doctrine and principles of lines. His interior designs were influenced by lines that create illusion. An example of his work is Amailienburg, a small lodge in the park of Nymphenburg Palace, Munich. It expresses curved lines and also planes that compliment each other. The room of mirrors made good feedbacks of its arrangement and entices the eyes of the different forms that it produces. Even his own room has different shapes and lines.
