These are all the parts that I needed for it :) Except the sides of the book shelf because I didn't realize I also needed them until I put some of it together hehe.
This was one of the less painful building parts so far.
Pretty straightforward building and I didn't find any problems except that I put the book shelf sides a millimeter too high so that the top stair shows a tiny crack but that's minor details really and doesn't matter at all.
