The natural aesthetics in a garden are a representation of natural elements by the gardener. They are confined, scaled down, and adjusted to human tastes, rather than being in the natural state of mountains and waters. In that sense, a garden expresses not only shapes, but also the ideals that humans want, and wish to see. The Gyeonggi Garden Exhibition was held at the Seongnam City Hall from October 7 to 9, 2016 under the theme of daily encounters with gardens. This study proposes the design of “Seshimwon” (mind cleansing garden), which is intended to express the exhibition’s theme of “daily gardens” and the aesthetic values of ordinariness, and the ideal relationships existing in abstract nature that the garden pursues through its spatial characteristics. To create the garden’s ordinariness and utopian landscape, pink grass was planted as a background to resemble the abstract images of the Hsien world and Arcadia. A washing machine as the entrance passage is a metaphor for passing through a cave towards a new utopia. In ordinary gardens, ordinariness is expressed by the relationship between the owner and visitors. However, given that there are only visitors at the garden exhibition, the scenery of the season substituted for the owner’s role in the relationship setting. In this way, this garden exhibition represents a new interpretation of how to express basic values of gardens and a given theme.
