This project stands in the most important location in the city of Taipei, intending to create here a landmark worthy of the importance of the location. The mixed-use building’s structure consists of the famous department store from the 1st to 4th floor and residential areas above the 4th. Our design approach is to understand the overall urban content and the environment, trying to find a way for the new architecture to enhance the urban content now and in the future. Our design concept is a brilliant diamond in the heart of downtown Taipei.
