Struggling with a challenge that I set for myself

@Simmingal there are some spandrels on the main veranda, but unfortunately they don't stand out. I might have to try some different ones, although none of them seem quite right. Maybe I need to look for some CC ones.

However, I did have to remove spandrels altogether from the rotunda part because they were causing all sorts of problems!

Thanks for your note regarding the dormer roof, I'll have a play around and see what adjustments I can make.
