Floor Plan Refinement & Detailing

I have an existing floor plan laid out in feet and inches and now need a fresh, expert eye on it. Your main task is two-fold: first, verify every dimension, tightening any measurement that drifts from true even by a fraction; then, position each window and door that makes sense. I need some advice on placement to make it simple.

I need help refining the geometry, align all openings with structural walls, and label them clearly so the plan is permit-ready. Once complete a clean PDF for quick viewing. Accuracy is king here—when I measure on site I want the drawing to match down to the inch.

I want a contemporary stying like this and roof like this because of the solar panels that will go on the roof. It will slope up from the front door, which is facing southwest. Not this floor plan though! See attached floor plan.
