Fragment a model in pieces?

Hi,

I've successfully created a tornado, visually and physically. It can pull and throw objects depending on the weight of the objects, the proximity to the tornado and the force of the tornado's winds.

Now I want to simulate destruction of multiple objects such as houses. Now, is my only solution to have hundreds of models for parts of the house, or could I actually break a model in pieces when the pulling of this object is triggered? I could then have a wall model, a roof model, etc. and just break them in pieces when it needs to be pulled in the tornado.

Thanks!
