DPL is the Detroit Public Library, located in downtown Detroit. As an old industrial city, the revitalization of the city has become a priority for the local government, and the renovation of the DPL can contribute to the revitalization of the city. The DPL block is very solid, it can give some sense of power. Symmetrical distribution on both sides can also give people enough of a sense of ritual. The project transforms the old building through volume logic, addition and subtraction, and the new library will bring an entirely new feeling to the city silhouette
