Yes, I wanted a lighthouse that my sims could actually live in rather than just a deco object.
One is limited to what the game allows when building. I don't think there is a way to make the lighthouse gradually smaller as you go up. I started out with diagonal walls, which didn't look right so...I thought..well, square will have to do...and it looked much better. I know it should be a bit taller but I had trouble with that also...as I said..we are limited to what we can do.
I found this, which is what I'm going for in the interior - WIP so not sure when I'll get to it ; )
