New Doors on a Crookie House

So the new french doors in the dining room have been installed. They look great. Or they will, but I can see the potential.

However, this week, our GC has told us that we need to buy new windows because ours are in such bad shape. And oh by the way, they need to fur 3.5" off of the living room walls because our house is crooked. I'm not joking. Three and a half inches!!! In case your house is plumb, furing a wall or ceiling basically means that they add 2x4s to the existing frame of the house. What a mess!
