This study suggests a plan for Methodical information service of nationwide Hanok by researching and informatizing current Hanok status. Despite recent Hanok market outburst and increasing demands for Hanok policy, there is still a concern over demolition of Hanok as a result of imprudent development. Moreover, the absence of Hanok statistics over the country impede systematic policies for Hanok resupply and preservation. Therefore this study aims to provide a effective plan for authentic nationwide Hanok status database construction.
