Yes. You can provide us a list of modifications or a sketch, and we will provide you an estimate to modify the drawings. Unless additional revisions are requested beyond the initial scope of work outlined, the estimate will be your total cost! A large percentage of bulders/home owners request some modifications. You can even order the standard PDF drawings, and we will send out the standard drawings. Then, you can request modifications in the future after you have reviewed the plans, met with builders/contractors, etc.
