Foundation

Foundation is an architectural object in The Sims 2 and The Sims 3.

Foundations are used to raise the level of the main floor and can be used over uneven terrain. In The Sims 2, unpatched versions of The Sims 3, and The Sims 3 for console, foundations are required for the construction of basements.

The foundation tool is used by clicking and dragging an a square area on the terrain. There is also a diagonal foundation tool.

Players can choose either a decking foundation, an elevated foundation, or a brick foundation.
