I do hope for one thing that the house can't be damaged or destroyed in anyway....

I would rather not comeback from a gathering more Dwemer artifacts for study, dealing with the political elite of Solitude or a mass killing spree to find that some dragon's burnt my house down.

I was actually hoping that our house WILL be destructible, would be nice to be able to destroy it and start over.

However, in the trailer, the guy said "place a permanent mark in the land of skyrim." Sounds like a hint to me you won't be able to destroy it

There's been no real structural destruction thus far, and I'm not sure if the game engine is capable of it. So I'll put my bets on the houses not being able to be destroyed.

Not going to happen.. Better luck in Elder Scrolls 6.. If that has physics and could handle destruction..

No.
