Frankenhouse - half pier and beam, half foundation

[ben3]

I am a new user (Architect). Watched a bunch of videos, but can't figure out the best way to do this.

My intent is for interior remodeling, but I would like to model the whole house.

My house is actually 2 houses. The original house was built in 1920 and is pier and beam. It is one story. in 1985, a second house was added on. This is built on a slab foundation and has 2 floors. Looking from the top, it is like an "L" where the newer house is the vertical line. There is a 3' opening between them with stairs (about 13"). Like a doorway with the door removed. Also, the ceiling heights are different in the 2 houses.

I am OK with just having a crawl space for the original house. I just can't seem to get the model to build correctly. When I adjust the newer part, it complains about the roof overhang.

I have not tried to build 2 separate structures and just but them up against one another.

Worst case, I will just model them independently.

Any thoughts or suggestions?

Here are some pic's. Outside, and inside of the opening between the 2 "houses". Note 1 from the old part, and one from the new part.

Make sure all Default Settings are correct for each floor including the foundation (in the case of the foundation you set its defaults to the Majority of the foundation as a whole leaving the exceptions for the minority spaces. before drawing those floor plans. Leave the foundation until last, concentrate on the first floor first, then the second floor. Then make sure all room dialog boxes are properly set on the first floor relative to the foundation.
Really learn what each setting is, what it is for and does before making those settings (do not guess, know before you go, this also covers "assumptions", do not guess, study and then practice on simple models before you apply that new knowledge to your house model).
