Earth as a fundamental aspect of the existing conditions of a site has/can/should have agency in design, both historically and today. The aim of this study is to describe the agency of earth in design as a common premise between the disciplines of architecture and landscape architecture. The thesis question is "how can the earth on site have agency on the design?" Thinking of the physical earth, specifically the topography, as one of the basic structures of the existing conditions, the earth should be taken as the most important condition that both architecture and landscape architecture use and share; both disciplines have to deal with context; they both have to deal with surroundings, and then work within systems that exist around them. As landscape architecture has been incredibly important to civilization throughout history, this project looks at different ways that earth has agency in design through important periods of history, from Greeks to contemporary design. While there are many examples in which designers have worked with the existing topography, there are other cases across cultures where people have drastically altered topography. Thinking about those designs, there are many possible answers to this thesis question from using existing hills to making mountains. This thesis explores the creation of an artificial mound, as a monument to indigenous people, in order to revive the missed parts of the earth and empower the ground. The thesis rethinks the whole ground, protecting the earth by turning excavated soil into an important earthwork. The design is not only about creating an earthwork for people, it also transforms invisible earth into a visible structure. Based on the practices of Native American mound builders, the earthwork stands for the values of diversity and equality in the US, creating a gathering space for all people made of the native earth/soil. / Master of Landscape Architecture / Earth as one of the existing materials of a site constantly affects the process of the design. This study focuses on describing and improving the use and understanding this material shared by the disciplines of architecture and landscape architecture. As landscape architecture has been incredibly important to civilization throughout history, this project looks at different ways that earth has affected design through important periods of history, from Greeks to modern design. Considering many examples in which designers have worked with the current land, there are other cases across cultures where people have changed earth. Thinking about different designs, there are many possible answers to this thesis question from using existing hills to making mountains. This design is an artificial mound as a monument to indigenous people and it is about reviving the missed parts of the earth in order to empower the ground, rethinking the whole earth and protecting it, turning it into an important earthwork that is not only about something for people but also making it into something which in invisible situations it cannot be. Based on the tradition of Native American mound builders, part of this thesis is to affirm the value of diversity and equality in the US, through creating a gathering space for all people that pays special attention to indigenous culture.
