How are your house building skills?

I nearly chose "I can put in the pool," and now I wish I had. I can build a box, but I struggle to put the roof on it.

I *might* become a decent builder if I practiced. I really want(ed) to build the house I grew up in, where my parents still live. It's not a terribly complicated design--a series of rectangles--but after spending an hour trying to get the basic shape without success, I got frustrated and went back to Live mode. I could only imagine how long it would take me to lay out the rooms. And then I'd have to figure out how to install the stairs to the second floor.

I have good pictures of the house, besides the images that are forever in my mind, but I can't translate them into a structure in The Sims. I'm impressed with those of you who can do that, and more.
