Stuttgart City Library
The site for the Stuttgart City Library was chosen in Mailänder Platz, an area that is perceived to be a future city center growing out of the location of the library. With this in mind, the architects chose to physically express the importance of this cultural center by giving the building a grand physical presence. The building takes the form of a cube with an edge length of 45 meters.
It is constructed out of pale gray fair-faced concrete that visually frames an array of 9 x 9 frosted glass bricks. The shell is designed as a double façade that includes the glass brick level and an inner mullion/transom façade as the thermal building shell.
The form and symmetry of entrance of the building were inspired by the “Cenotaph for Newton” by Étienne Boullée, but the heart and core of the library follow the design of the ancient pantheon.
Protected by a secondary façade, the cube-shaped room is situated in the middle of the building and is illuminated by a central roof light. In the center is a 1 m² fountain that ties the space as a meditative area.
The gallery hall is a five-story space, square-shaped and surrounded by a shell of books. The interior circulation is arranged in a spiral among the reading gallery areas, designed to be flowing promenades flooded with light from the glass roof.
The forum, a third central room, is located below the heart. This is an event room which is in proximity to the light railway line that crosses the first and second basement floors.
