Thank you. I have been racking my head for an idea for my library in my skybox now after seeing yours. I am flooded with a million ideas! Awesome library indeed!
Amazing man, and props for building it in survival! The funny thing is I started something very similar to this yesterday, with the pillars and the same roof xd
There are no plans for putting it up for download.
I hope this might give you some inspiration for your own build!
