A Study on the Parking Space Planning for the Office-to-Residential Conversion - Focusing on the Office of the Old Downtown of Jung-gu, Daegu -

To revitalize the declining downtown, it is necessary to improve the settlement conditions and increase the settlement population. Consequently, this paper proposed a plan for urban regeneration to convert the vacancy of the city office into urban housing and analyzed the solution for securing the legal parking space for the conversion. For the analysis, seven plan prototypes were set up by classifying all offices in the old downtown of Daegu by the number of floors, slenderness ratio, core type, and typical floor area. Based on this, if the entire office vacancy is converted into urban housing, it is required an additional 15-30% of parking, and if it is impossible to expand additional parking within the site, parking space should be secured by utilizing existing urban assets such as underground urban parks and public parking lots. Meanwhile, if an office vacancy is converted into a complex facility that combines residential, neighborhood facilities, office(SOHO), and community facilities, legal parking is satisfied with existing parking space without further expansion. To this end, the parking expansion plan required for the converted housing is necessary for sustainable urban regeneration by facilitating the universal applicability of the office-to-residential conversion and increasing the urban housing rate.
