Structural Coincidence of Architecture, Audio and Visual
Practices of IVAAIU City Planning in Seoul, 2015
Donguk Agos Lee, Principal of IVAAIU City Planning
Architecture, audio and visual can be categorized as a different medium. Architecture is a medium that embraces human semi-permanently in a solid form. Audio is a medium that interacts with human instantaneously in a flexible form. Visual is a medium that exists around human semi-permanently or ephemerally in an animated or fixed form. In an urban environment each medium has been possessing different area, time and groups of people to interact, therefore, each one has distinctive power as a medium in a physical environment.
The same feature these three media share is a structure. Architecture, audio and visual are all formed with an evident or ambiguous structural logic. Physical elements, building materials, notes, light components and such things, are formed based upon a certain logic of structure and create an architectural, auditory or visual result. Regarding the different and common feature of these three media, when structural logic of these media are coincided spatial experience in an urban environment can be hyper-effective.
This explorations and practices of coinciding architecture, audio and visual can be found in the history of architecture; Le Corbusier, Iannis Xenakis and Edgar Varèse worked on Philips Pavilion In 1958 Brussels Expo and aimed to create structurally coincided Architecture, Audio and Visual. Le Corbusier stated to the Philips electronics company to create a pavilion with “light, color image, rhythm and sound joined together in an organic synthesis”. Iannis Xenakis and Le Corbusier designed the architectural structure aligned to Edgar Varèse's Poème électronique, which includes Iannis’ interlude, and Le Corbusier composed visual elements for Poème électronique. Juxtaposition of these three media in one pavilion created multi-faceted experience of time and space. 
IVAAIU City Planning has been doing practices of simultaneous construction of structures with three media. Even though the sequences of constructions differ in each project, these explorative coincided constructions have processed based upon same structural logic.
Borderline XXI project, an architecture renovation project of IVAAIU, started with the architectural concept which is to add deconstructive layers to rigid cube structure. During the process of construction, the audio track that is dissolving and reconstructing one note into deconstructed sound was created by Eexxppoann, who is also the architect of IVAAIU. Then the programmed visual which shows from simple dots to deconstructed atmosphere was made by Sangchul Nam, the new-media architect of IVAAIU. Using the surface of building and interior space of architecture, this visual and audio was projected on the architecture for a certain period. Afterwards, the architecture has been used by residents and the sound and visual has been heard and seen by anonymous listeners and viewers.
Monument of Collision, a conceptual structure of IVAAIU, started with the visual structure of photograph of Seungwoo Back, which is the juxtaposition and collision of structurally distinctive objects in an urban environment. Than this structure of photo architecturally reinterpreted by IVAAIU; an architecture structure is created by clashes of ten different structures of steel and light. Sharing the same structural concept, the audio track which is created by ten different structural clashes has created by Eexxppoann. This architectural structure was devised for temporal usage during the exhibition of Seungwoo Back and now dissolved, however, the audio and visual are still in existence in different formats and experienced by another listeners and viewers.
Other practices exploring Structural Coincidence of Architecture, Audio and Visual of IVAAIU City Planning are still in progress to find out effective coincidences between media for creating the urban environment that interacts with public in a hyper-complex level.
