Completed in 1970, the Samilro Building (currently Samil Building) holds immense historical significance as a symbol of Korea¡¯s modernisation and as architect Kim Chung-up¡¯s first office project. As the nation¡¯s first high-rise, it had aged significantly over 50 years and urgently required upgrades to serve as a modern office space. The design team pursued a renovation focused on preserving the building¡¯s heritage while complying with current regulations. The goal was to maintain Kim¡¯s original vision while reinforcing the internal structure and upgrading the curtain wall façade.
