This paper deals with second Dresden Hoftheater by Gottfried Semper. The purpose of this paper is to show Semper's architectural manner which he acquires in response to the main theme of Theater Reform. Therefore this paper clarifies the architectural composition of this theater on the basis of analyzing the relation between blocks and surface. Semper disconnects the outside from the inside, packaging each block with a surface that is given meaning by iconographical elements and keeping the theatrical elements in separate blocks. And this theater narrates theatrical character by means of iconographical elements free from the contents of blocks.
