This is probably not exact. A lot of guesstimating was used with this, since there's only two shots of the village in the Minecon Earth footage.
Also, 1.14 is the update coming at the end of 2018, and 1.15 is the Village and Pillage update coming early 2019. More information on this Reddit thread here.
After watching Minecon Earth, I looked and realised that there's no obvious new blocks in the village, so I figured, "Why not create it so that everyone can explore it for themselves?" so that's what I decided to do. A few hours later and I replicated everything. It probably isn't exact, but it's as close as I think I can get.
Here it is! This was built on a server in survival, but I've trimmed the world so that it only contains the village chunks to save download time.
What about the desert village?
At first I was going to completely not do it since I much prefer the look of the plains village over the desert village, but the more I look at the desert village, the more I fall in love with it, so I think I will soon.
