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 version of only the pub called "Ye Olde Pube" so people can have a look and use world edit or whatever to import it into their own world. I will upload another version where the island(s) are included but up until then, feel free to use this version for now.

Made some small changes / improvements but tried to stick with the main building.

Update: 18/04/2022
Redid all the work and moved to a super flat world with structure & mob spawning, time and weather disabled to reduce the filesize.
Updated version with island here:
