The main goal of this project is to create and redesign of the GW2 building with parametric design by the purpose of fit into the space of the Bremen University area.This building made by 20 number of G while the ideas behind this project are a redesign of the GW2.We decided to make a general shape of G because of Two main goals: First GW2 is starting by G and second, this is the best opportunity for dividing inside and outside of the project in two-part space, although we used the shape and parametric design to keep it fitted into the design of the university. By research, we found that GW2 was the first building at the University of Bremen, with a special history. Also, this history is the reason why we decided to use G shape.
