This study examined measures for applying proptech to provide property services to both smart cities and smart villages from the perspective of national land and space management. Proptech had been limitedly implemented in the field of urban property. In this regard, this study suggests that a range of regional proptech applications should be expanded to non-urban regions to ultimately provide proptech-based property services to all of South Korea. To this end, this study analyzed major characteristics of sub-projects of the smart challenge project executed by the Ministry of Land, Infrastructure and Transport. It also examined project execution strategies by classifying smart challenge projects selected for application to small local cities in rural areas as local models led by local governments and base models led by branch offices of the Korea Land and Housing Corporation. According to the models classified, the study analyzed cases of proptech application in the property industry regardless of regional hierarchy to enhance daily living services for residents, reduce the smart information gap, expand the smart market, create new industries, and ultimately change national land and space under the smart city system.
