Identification of a Bookshelf  

Looking for information about the bookshelf pictured below. It seems to be made of vertical wood supports with horizontal shelves. The shelves are held up by a visible steel band, and probably some support underneath. I first saw the images at fvf, an interview of Uli Mayer Johanssen, and figured they must be custom. However the darker version of the bookshelf, also pictured below, is from a different house so I assume it isn't custom. The pictures aren't the highest quality, sorry about that.
