Model a basement window vault.

[Doug_N]

In creating an as-built set of plans, the existing basement windows are just under the ground floor sub-floor.  

 

This is pretty common in my area so that the first floor can be close to the grade limiting the number of stairs to reach the ground floor, and at the same time saving the cost of window wells.  

 

I am perplexed on how to model these that doesn't end up with cutting the floor above.  I couldn't think of a way to do this that didn't involve a hole i the platform, then using a material area to repair the hole.  Any ideas?
