Attached garage second floor different level?

[apex_predetor]

I am modeling an attached garage onto my existing house.

I would like the attached portion roof to be slightly lower than the existing structure but I am having a hard time figuring out how to define that room elevation to be lower than the others on that floor.

Thanks for any help.

This is what I am trying to accomplish.

I can't seem to figure out the garage addition roof height?

I can't open your attachment.

Ceiling height controls the roof height if you do it automatically. Manually, you can put the roof anywhere you want by adjusting the baseline height of the roof.
