Stockholm Library, located in Sweeden, designed by Studio ST Architect. When looking for intelligent structural solutions we sought to use the inherent structural logic of the library – the bookshelf. Instead of creating a building and filling it with book structures (shelves) why not use the book structures as a building structure? This programmatic structure combined with the site constraint led to the development of the overall structure: eight large cores support a three-meter high space frame. Off of this preliminary structure a dense grid of 1×2 meter steel cables is suspended. This grid extends throughout the building to support everything from the façade to the book shelves. The cores shift from their original grids to keep a six meter distance from the subway tunnel below grade.
