Thanks Mike for sharing this nice ranch made for people who like round things. Fortunately, all the walls inside the house are not round, otherwise it might become difficult to furnish it! [;)]
In my mind, the last step of a stoop (nice to learn a new word) is larger but of course, it's up to you!
I appreciate also that you try the new textures of the recent libraries update. It's good to see how they render on a real project.
