Be nice! Though that was Hilarious!

Ahem! OP What I like to do when a fast shack needs to be built it place a single floor piece down at the highest point on the land your in. Then expand that to 2x4 or 2x6. Put in a door at one point then use the wall segments to build up the height.

After that roof it. Next you can now break a wall to replace with a door, or break walls to replace with half height walls to get a kinda window. I'd keep all corners solid but feel free to do it your way.

Lastly go outside and put support posts on any exterior area that's hovering over the land.

The reason I say that is once done you can go back to the original tile you started from remove it and put a fireplace against the bare earth there.

You get 100% of your materials back when you break stuff so do not be afraid to experiment and reposition.

Once you have lit your fire you may have to experiment with the roof to make a chimney for the smoke but by then you ought to have a feel for things

Alternatively drop you work bench by a ruined house and repair and expand it till you've got a feel for the build mechanics
