in order to model a wall with two (or more) horizontal sections/materials and have doors and windows work as normal, i would probably use a complex profile with the different fills set to different materials (see attached, left). you can even use one fill in the complex profile window and add nodes to have different materials (see attached, right).
from your reference to construction phases, i'm thinking you're looking at the construction simulation function. if that's the case, and you want the different levels of wall to appear seperately than i think rod's suggestion of seperate walls with empty openings at door window locations is probably the way to go; i think you may also want to have separate layers (with different priority settings) for each level.
