"I saw a house destroyed on the road" is acceptable, but probably doesn't mean what you think.
It mean that the house was on the road (odd, houses are normally next to the road!) and you saw the process of it being destroyed. You can clarify this with "being destroyed":
I saw a house being destroyed.
I watched as the house was destroyed.
It is not possible to treat "waited" in the same way. "I saw you being waited" does not mean anything, because "wait" doesn't have an object. "I saw you waiting for the bus" is fine, but not "waited".
It is possible that you wanted "destroyed" to describe "house". The adjective "ruined" would be better: "I saw a ruined house"
