This study illustrates a prototype proposal and its evaluation for the development of floor plans in the condominium housing remodeling. For this I evaluated the survey of the residents of the 'K' town in Joonge-dong, Nowon-gu, Seoul, against the proposal which was developed based on the resident's pre-survey. The result includes that the residents' preference for community actions such as the removal of fences which are reviewed as negative, whereas the introduction of a fitness center and community facilities in the library are reviewed as positive. The residents preferred the open space by the piloti structure, although which is the wall column structure, where they anticipated a rest area, sports facilities, and bicycle drop-off spots. The sidewall proposal in the main building and the full use of the roof floor were underestimated in terms of design concept. The research also illustrated the residents' desired space planning options, those tending to use of space 'B type', personalization 'C type' and spatial size 'A type'. Residents responded positively to the introduction of the 'Alpha' space in which two households share one space that could be used for multiple purposes such as a rest area, an environment-friendly garden, and hobby room, etc, and also there is another possibility it plays an important role to the sociality in community.
