Thanks for the link. That is along the idea of what I'm saying, but only like 25% of the way there. I want the entire structure to be editable, so I could have a dome for a house if I wanted, or a house that looks like it's made of rock, or whatever. Like the entire shape/material type. This adds a bit of a change in those regards, but more looks like that stuff is plasted over top of the current house, rather than a house built entirely different.

To add to what I am saying, I don't need there to be sliders necessarily for changing the shape, but at least options that can be added together to create 100's of possibilities.
