In this research about modern building designs in South Korea, the focus was on how facades, the outer parts of buildings, can be improved. The study looked at different ways facades can be made more functional and aesthetically pleasing. Five important trends were found in modern architecture: improving interior and exterior spaces, creating visually appealing facades, connecting buildings to their surroundings, using adaptive facades for better performance, and enhancing public spaces. These new ideas aim to blend traditional and modern aspects of architecture, making buildings more harmonious with the environment and better for people's daily lives.
