This paper is to evaluate an open space on university campuses enclosed within buildings, with respect to building elevation a wall of an open space including outer wall materials and window forms and an open space itself. It uses case study methods to periodically know specific details about open spaces and surrounding buildings elevation. It was found, at first, that it was emphasized vertical elements on window frames as well as building elements in an era of the 1910's to the 1930's. It, however, was changed into emphasizing on horizontal features in the era of the 1960's to the 1970's. Meanwhile the period from the 1940's to the 1950's was a turning point. The horizontal style was continued until the 1980s and the style was changed into various style mixed with various types. Secondly, an open space was recognized as a valuable design criteria for a construction of buildings in the 1930s to the 1970s. It was, however, a forgotten criteria during the late 1970's and the 1980's because of short age of the construction budget of the government. In the 1990's, the importance of open space design reappeared on the design of a block plan. Thirdly, a design style of an open space was authoritarianism using symmetrical and magnificent style in the 1910's to the 1930's. The time of 1945 to the 1950's was a turning point from authoritarianism to an idea of efficiency. In the 1960's and the 1970s, an idea of efficiency emphasizing their functions was prevalent to the design of buildings and open spaces and this trend was continued until the 1980's. A romanticism was realized on the design of an open space and surrounded building's.
