Need help with creating a building system (1.16.5)

[RonKon]

Hello. I want to make the building system where constructions is made out of multiply blocks, and contains various variables such as material and durability.
For example, when player places certain block, there will appear new construction, and when any of its block damaged, durability of entire construction will decrease.
Also i need it so player can upgrade the construction and demolish it.
How can i make it, with taking into account that there will be many of constructions, and they needs to be saved even on server restart?
