Recently our country highly evaluate cultural value of modern construction. Before and after Japanese imperial period, diplomatic equipment, commerce equipment and brand-new modern construction of Japan and Western came into our country coercively. Especially, modern construction placed in center of the city, as previously stated, was a construction field of historical disgrace. So it leaves alone or transforms to high technology because of well located. Selctive reception of the past makes difficult to know about rightful modem, furthermore it is difficult to expect rightful future. Accordingly, I write this. paper for the purpose of presenting the space application blueprint of 'Jung Myung Jeon' of modern construction designated as the cultural properties in Seoul. According to the project, 'Jung Myung Jeon' will do a role as the keyword which is important connects a past and a present time it presents. Then modern construction 'Jung Myung Jeon' which has a culture value will develop continuous with the city.
