The project was a competition for build a modern Archive in Kassel, important city in Germany. This Archive must be included a library, exhibition area, bar cafè, restaurant, congress room and others rooms. 

The idea is to open the building connected the pedestrian street from the chirch and from the street perpendicular to the archive  creating a public space in front of the main entrance. People are naturally tempted to enter the building through this link.  From the plans and the sections you can see a big atrium inside and the main stairs that link all of the floors from the ground floor to the fourth floor. These stairs are also public space where people can sit at the beginning or end of the flight where there is a collecting space.

The double skin outside is corten with holes that allow the entry of natural light. Corten material is special steel that has low maintenance and can cover the building from the agents atmospheric. This material is also connected with the meaning of the archive because the brown color remind some thing that is there from a long of time. The roof is inclined to “cover” imaginatively the existing building behind and for get solar radiation for use renewable energy.
The main structure is reinforced concrete with pillars and load-bearing walls.
