How do you build Second Floor?

[AiD_90]

I have the original house and I am at the point where I can get a Grafter. But the instructions on how to build the second floor is non-existent.

Can anyone help with what steps I need to take? Do I need to remove the roof some how or do I simply add stairs? Etc, etc.

Unless you have made that house bigger I suggest you sell it and start fresh with a bigger layout. OR upgrade the size of that one, put your stairs in and you have to buy the rebar framed walls for the second floor completely closed in to give it a roof. Have fun taking down the first houses roof lol.
