Hmm, is it possible to convert a static Object like a door to an object with life so you can smash it?

Search here: http://www.creationkit.com/ObjectReference_Script for damageobject, getcurrentdestructionstate, ondestructionstatechanged and cleardestruction. You can find an example of it's use in Mineorescript.

Thanks for your answer.
Does that type of damage advance your skills though?
I am looking for a method so the player can damage the object like he would damage a mob .

Not by default. You would need to add that part yourself. Indeed, you can't aply it directly, you would need to use a method for detecting the hit first, like the onhit event (which needs to be handled with care as continuous damage spells launch a lot of events very fast, a state change is needed to avoid the event processing more hits for a brief while afte each time it runs).
