I think I already do, but the threshold angle is quite small.
Just get sharper furniture!

The very first thing I did was to parametrise buildings so they could be made
randomly with a degree of variety. And then I got bogged down with making them
polygonal, then with streets, then how to get those streets, then the various
edge cases that crop up...!
Since most of the groundwork is now laid, I can concentrate on colour, texture
and detail. Window sills via repeat object textures, roof styles and furniture
(aircon, water towers, masts etc), and some more building styles and sub-types.
I also really want to do some more work on the height selection, to get some
interesting cityscapes with 'hills' and 'valleys'. It's been a bottom-up
approach, so it's only recently started to all come together :)

You probably did not see the World's narrowest house...
It's 5 stories high, and have only a single window on each top floors.
The ground floor have only a single door and a narrow window. Go inside,
and you can easily touch the opposing walls, everywhere.
It's to narrow for a double bed.

It's looking better and better <*sigh*> You've also solved the need for
'recessed' building sections on top of the 'main' buildings. I still haven't
tackled that (well, with my newer 'buildings as height_field faces' scheme,
anyway.)
Your approach is well worth the effort!

Well, I know Amsterdam has one at least. ;-)

Do you mean the 'compound' buildings with the decreasing sizes? Those are
basically a specialised building type that just creates two or three
sub-buildings with different versions of the base polygon. Since the building
construction already offsets polygons extensively, it wasn't a lot of work to
add this.
> Your approach is well worth the effort!
So far so good. But I think your buildings are much more detailed and realistic
on an individual basis, which I'm going to struggle with later on. It's
interesting to compare approaches on similar but unrelated projects - there are
indeed many ways to skin a cat!

I can confirm that no cats were hurt during the development of this project, and
that all skinning incidents have been metaphorical in nature :)
