UNStudio’s design for the Hanwha’s headquarter building incorporates the renovation and remodeling of the facade, the interior of the common spaces, lobbies, meeting levels, auditorium and executive areas, along with the redesign of the landscaping. Several important variables were required to be incorporated into the redesign, most essentially the surroundings, nature and the environment. UNStudio’s concept for the project resulted in the design of a responsive facade which prioritizes and integrates groups of key parameters: program (exterior and interior), indoor climate and environmental considerations.
