I have split it into a new topic as it really has nothing to do with you other post.

If the wall is under the stair then you can try a Solid Element Operation with the stair as the operator and the wall the target.
Subtract with downward extrusion.

If that does not work (some stairs are not scripted as solid elements) or the wall is not under the stair then place roof, slab and/or morph to get the cutting shape you want and do the same as above.
Then hide the operators in a layer that you can turn off (don't delete them as there will be no SEO then).

As for the hole for the door just use an empty door opening.
