Anatomy of landmark. Research and design equal to each other and connected well is the main character. The starting point of the design should come from the urban research. My partner and I summarised the conclusion of the research, aiming to build a tower owning both tradition and modern public actietivities combined （library and market)at the corner of which is the recessionary old modern-style CBD of Madrid. It is for gathering different people, connecting infrastructures in the neighbourhood and public facilities near by (the Stadium).
