The international competition for the National Museum Complex Masterplan of Sejong Administrative City was conducted in two stages to ensure an integrated vision. The first stage focused on the overall development of the 190,000m©÷ site, while the second stage evaluated detailed masterplans and the design of the first-phase facilities: the National Children¡¯s Museum, the Integrated Storage Facility, and the Integrated Operations Headquarters. Junglim Architecture, in collaboration with the Canadian firm Office OU, was selected as the winner for its entry, Sejong Museum Gardens.
