Mod description
This mod adds plenty of building blocks that fit with many different building styles and aesthetics.

Why would you like the mod added?
Some of the blocks that this mod adds are really unique, and I would like to be able to utilize them in builds on my server.

Screenshots if applicable.

Thank you for the suggestion, I'll have a look :)

Love it, very unique, adding it :)
