I would love to check out this Craftsman Home and check out how to build it but i'm not sure how to put it onto a leval and see. Could you guys help me out guys?

Use a map editor and copy a certain build into a schematic. Then you load up the world you want the build to be in. Then you place the schematic into the editor, position it to where you want it.

Its pretty complicated to explain, but videos help, and YouTube and Dailymotion tend to have lots of helpful videos.
