How are your house building skills?

I am so bad at building and get overwhelmed with both building and interior that I get really discouraged. So, I'm in between I can build a box, but I also give up, but then try again.. just to get overwhelmed and give up again. ? I really wish that we had roof presets, though. or Blue prints so that I could try practicing. Would love something like the Sims 3 one, but more in-depth.
