バルセロナ・パヴィリオンの平面にみられるグリッドシステムについて

抄録

The German Pavilion at the Barcelona International Exposition in 1929, designed by Mies van der Rohe, is an early example of minimum architecture which lessened the elements of construction to the limit. There are five schemes of this building, which have changed little by little. The purpose of this paper is to show that the grid system was used in early drawings and the form of the main composition elements and their arrangement were determined according to this grid. The conclusions of this study are as follows: 1) Although grid lines were not drawn in the early schemes, it is strongly thought that the grid system was used. 2) The grid lines which equally divide 12m, the inside measurement of the east-and-west wall of the pavilion change as follows: in the first scheme there are nine grids at intervals of 1.333m, in the second there are twelve at intervals of 1m, in the third and fourth are eleven girds at intervals of 1.09m, and in the fifth at intervals of 1.1m. 3) Most of the positioning of the walls and the glass screens have been based a grid system, but some have been based on their specific size (12m and 7m, for instance). 4) It is thought that the fourth scheme drawn with an even grid system was preferred by Mies. However, an irregular grid system was used, partially to correspond to the site in the fifth scheme.
