I made some portable houses in Minecraft! There is a Starter House, a Desert House, and a Modern Mansion that can be placed and moved to anywhere in your world. The way it works is super simple, to craft the item gather all the resources needed to build the house. Don't know what you need? Type /trigger [​the house] and it will give you a recipe! Throw those items onto a block and it will give you a scale model of that house! Then place it anywhere you want and the house will be placed right in front of you!
If you just want to mess around, type /trigger houses and it will give you the scale model for all of the houses, without needing to craft them.
Important note: In order to pack up the house all items within a certain radius of the house gets deleted. Make sure the area is clear of valuable items before you pack up the house!

Install the datapack as you normally would. Make sure you have the resource pack enabled as well.
In order to get the houses into your world paste the .nbt files into the structure folder. To find it, navigate to your save folder in
.minecraft/saves/[​YOUR WORLD]/generated/minecraft/structures
If you do not see the "'generated/minecraft/structures" folders in your saves folder, you can create it and it is safe to do while the world is open.
