Architecture and its infrastructure act as a mediating tool defining the world around us by structuring experience. This thesis will define the consequence of building and how designers structure experience by opening and obscuring creating physical, intellectual, and even political boundaries. The vehicle of the study is an addition to the iconic North Dakota State Capitol Building in Bismarck, North Dakota. The addition includes interpretive space at the base of the current structure as well as new entry condition and vertical circulation. The new architecture questions how one makes additions to existing pieces of architecture and studies how the manipulation of paths and frames impacts the perception of space. The study also questions the issue of site and how architecture acts as both an object looked at, often from far distances as well as looked through, sculpting views of the surrounding horizon.
