Amazing Book Space

I couldn't help but share the amazing book/lounge area devoted to reading!! I'm wondering how much work it would be to get this put in my house! 

My only issue with it is, I would want to get some light installed in there too, as the wall I have in mind for it doesn't have great lightening. But look at the storage! All those shelves and a few drawers!
This is such an EXACT replica of what I want! I wonder how much the materials would be??
