Ace_Monkey, curious, what are you trying to learn how to build? Do you have a specific style or idea in mind?
Over the years I have been working on a large schematic pack that enables people to quickly transform their worlds into playable maps. IE modular tunnel and path schematics that you can snap together to lead a player around. I also have a large tree pack, lantern pack, teleporters pack, dungeon tunnel pack as well as others. If you are interested you can download all of these already at:

This is an open source map where you can d/l it and change it however you like. Make it your own. If you like that or anyone else for that matter, I have the next generation version of that world ready as well. I just haven't uploaded it yet.
