I designed this piece to be one of the shelves featured at the Hapa Collective in Seal Beach, CA.
The shelf hangs on the wall via brackets welded to the shelf, spaced to overlap the studs in a wall. It can also hang on drywall anchors. When you put books on the shelf, the books hide the brackets. It's very sturdy and easily handles being completely full of books. It also includes spacers to allow the books to take the form of the shelf.
This shelf is made of aluminum and comes in 2 pieces which must be assembled with bolts.
The surface design on the aluminum is a an engine turned texture I've developed over the years. I use a secret sanding disc and a drill press to sand circles into the metal. It is very time consuming and tedious to make this texture, but it is all worth it once the texture is there.
The books curve to the shape of the spiral, and the grinded surface design dances in the light. This shelf has a dual purpose in that it both decorates a room, as well as holds books.
I personally installed this bookshelf, and it took me about 15 minutes to do it solo.
