I think it is fundamentally wrong to start such a project with façade panels. Unfortunately, it is a common mistake of non-professionals to start with something you have no idea how to implement, according to the motto "get the stones out of the way". In other words, you brainstorm all the things you want to do, and then see where you can check the "I already know roughly how to do it" box; in the next step, you formulate questions from the unchecked lines of your plan and ask them of the all-knowing Internet. It sounds logical and clever – but, unfortunately, it only seems that way. Because the details remain details, and thus a tail from which you shouldn't stick your horse out. My advice is the tried-and-true order: "Build (the main thing) first, then (the aggregate of the existing building, alterations and additions) do the hair and makeup."
