The representative art world of Buren is defined by a key element, the vertical stripe of 8.7cm, that alternates between white and colored. The artist considered stripe as the most neutral form of visual expression that embodies no meaning and believed that its mere presence can be seen as a work of art.
The intended role of stripes becomes predominant in his In-Situ works based on site-specific installations. Pursuing art practices outside the established institutions, Buren overcomes the formal limitation of stripes by setting buildings and their surrounding environments as the canvas. Based on inspirations from the space, Buren externalizes its physical and relational elements. Here, the natural elements such as light, air, and wind become crucial resources to bring his artworks into completion. The concept of “site” that overarches time and space holds significant meaning for the artist. The artist strongly claims that his works must form a complementary balance concerning space and believes that the active participation of the audience enables it.
