Building Basement Stairs Through a Foundation
You can build a World Adventures basement under a house with a foundation that is accessible.

You can place a floor tile on the empty ground square. Yours sims will pause at the transitional ground square, but it will work. If you can't get your sims to go to the basement, try clicking on the basement stairs and then "use stairs." I have some screenshots for a little more clarity:
