After finding out that the following download requires a plugin to work, just to have a look, I decided to go through some videos, take a lot of reference pictures and build it by hand in creative mode.

I decided to upload a world with the pub called "Ye Olde Pube" from the Origin SMP so people can have a look and use world edit or whatever to import it into their own world. It took me at least 8 hours to build the pub itself and another 3 hours to do the floating island section.

Made some small changes / improvements but I stuck with the original building as far as possible.

The big differences are that I made the floating island myself and took inspiration from Ph1LzA's version so it's not exactly 1:1. Mainly because I got too tired to spend more time on researching the exact position of each block.

Feel free to leave some feedback and let me know what you think.
