Our home has a detatched garage and a very long driveway. We are hoping to convert the garage to a master bedroom and extend the side of house over the drivway and connect the detatched garage to this new addition. The new addition over the driveway will most likely be a garage, since we are converting the existing garage.

My question: Will we have to tear up the driveway or can the new additions foundation be built directly on top of it?

The foundation needs to be set below your frost line for one and secondly, the driveway will not support the load of a building on top of it.

Welcome!

Unfortunatly no, a house foundation and a driveway are differing. A proper foundation with appropriate footing need to go under the house addition.
