Darren-Cambridge posted a topic in Q&AWhat is the best practice in order to explain to home owner and contractor Changes in building from Old to New. Example the second floor of standard house. We wish to move non-structural walls expanding a hallway and dividing a bed room into a study and small laundry room. Is there a way of greying out/ ghosting original walls showing new layout to show the benefits in size and flow? This will help with visual types and keeping track of changes being made. I am guess this would be done with a layering detail?
