Barry said, "Do you have an architect? They plan/design & oversee the general contractor but for a small residence again they're usually way to costly."

Barry also said a LOT of other things. That's why they are "costly". However, given the number of times I have looked into sad eyes and told people that they have been screwed and can't do anything about it because the contractor is within the plans & specs and contract, I would check on prices. Even if you just have a draughting (drafting) service do up a fairly detailed set of plans, it is money well spent.

Please keep us updated on this project.
