European Strategic Planning Agency project is located in Strasbourg/France as a “think-tank” complex. The context is significant owing to its closeness to the European District of Strasbourg which is the center of Europe and the union. The city includes planned green areas, agricultural fields, dense urban settlements, and scale differences of built environment. The site is an intersection point of green and blue matrices of the city. It is aimed to design a sustainable complex as an interaction node of nature and Europe for the people of Strasbourg, people from all over the world, researchers, and the youth population.
