Abstract
Cities are defined by variety and complexity; their representative building type, the tall office building, is usually quite simplistic in space and program composition, which creates monotonous working and living conditions for its users. This study aims to provide an alternative to such typical settings by injecting new programs into the singularly purposed floors and creating various visual and programmatic interconnections among them; through the strategy of montage of collision, building new relationships among diverse entities to generate new situations and meanings through their differences was intended. Responding to contemporary demands for sustainability, this project was set up as a renovation of pre-existing, spatially neutral structure in a central business district setting. Leisure programs necessary for urban office workers such as gyms and cultural facilities, choices based on research of actual demands were inserted into the existing office structure; various surreal situations were created inside the building by actively promoting relationships among different programs in terms of visual connection, spatial links and movement. While this will help to increase the value of tall office buildings through idiosyncratic architectural features and to respond to the increasing problem of office vacancy rates in the emerging era of low growth, the ultimate aim of such a proposal is to provide a dynamic spatial and programmatic experience to its users while reminding them of the sense of excitement that brought them to the city in the first place.
