If you've rebuilt how did you go about doing it?

I did a full redesign after the Christmas event finished but couldn't bring myself to press the nuke button, so what I did was to move all the building to the opposite side from where I was going to start my re design, I clumped all buildings of the same type together, once all the buildings had been moved I then stored all roads and decorations etc before starting from scratch, one thing that I found useful that was recommended by other forums members was to take a screen shot of any areas that you like and want to rebuild the same, makes it much easier to do.
