Since 1.14 has so completely changed NPC Villages, I wanted to build a Plains biome village that contained every new structure in a nice, symmetrical layout.

This is a link to the list of structures that I included (I think that's all of them):
https://minecraft.gamepedia.com/Village/Structures_1.14#Plains_biome_structure_variants

The village measures 128 x 128 blocks (or 8 x 8 chunks).

The main buildings are arranged around the perimeter, in the outermost chunks.

The 'Town Center' structures are at the center. However, since this is a 'super-flat' world, there wasn't room to place the bottom of the Well at the center of the village.

The farms and animal pens are in between.

The 'medium houses', 'big house', and 'stables' are to the North.

The 'small houses' are to the South.

And all the different 'Profession' houses are divided roughly in half and placed towards the West and East, in alphabetical order, going clockwise, with two block spaces between them. I also placed an oak sign next to the front door of each of these structures, stating the profession of the occupant.

Unfortunately, the 'Farmer' wasn't given his own house, so I imagine they live in the 'Small Houses' to the South.

I haven't let any mobs spawn in (eg. Villagers, Iron Golems, Cats, Farm Animals), to minimize lag.

I've left the 'Structure Blocks' in place for all the structures (except the lamp posts), in case you wish to know their technical names. You can also view their 'bounding boxes' by clicking on the structure blocks and setting this option to 'On'.

I've included a few small Pumpkin & Melon farms, just to try and fill in the space.

I've included four Campfire areas at the center of each 'quadrant'.

I've included four basic Oak Trees to fill in the corners of the village.

I've included four Scarecrow statues on the large farms because I think they look cool.
The credit for the scarecrow design goes to 'Magmamusen' from YouTube:

The world is a basic, Super-flat world with 'naturally-generated' structures and the 'bonus chest' turned off.

The seed is: 1

I have set the following:

/gamerule doMobSpwning false
/gamerule doDaylightCycle false
/gamerule doWeatherCycle false

If you like this idea, may I suggest you create a similar 'Complete 1.14 Village' for the other village types (ie. Desert, Savanna, Snowy & Taiga).

Any questions - just leave a comment below.

Thanks everyone, and I hope you enjoy! :)
