Regarding modern roadways and viaducts that pass around medieval city cores, it's fascinating how they can be seen and still not seen. I tried to do this in Cities Skylines II for awhile, building very narrow streets in "organic" city centers with low-to-mid density, and then transitioning to a new city grid around the old center. Finally, superimposing highways and tunnels without destroying the original historical core. There were some beautiful results, but the traffic jams were astounding, even with limits on the city center roads and highway exits. This is the way cities actually grew, so to me it's much more interesting to simulate than a "perfect" city built all at once. One thing that was fun in SimCity 3000 was that certain technologies didn't become available until you had a certain population. I would almost wish that a city-builder now would allow you to take that to the extreme: Spend 200 years with horse-drawn carts before you can pave a road, and then figure out what to do with the mess. But more than anything: Oddly shaped buildings that fit into oddly shaped lots, which are not limited to hotdog stands.

Haha. I myself tried to play CS like that. Start with a historical core. The thing is the way the game is implemented buildings only have rectangular footprints while in reality buildings occupy the spaces more organically. I actually spent quite some time on google maps trying to see what pattern historical buildings followed to fill in spaces but couldn't get a definitive answer. I drafted it at some point in sketchup. Here is the result

		That's very cool! Thinking about historic city centres, like Prague, the presence of courtyards is also really important. But what often seems to happen is that several smaller buildings will conform their fronts to the curvature of the street, being more or less rectangular themselves, but not as deep as half the block, so that they form natural courtyards between themselves and the buildings on the opposite sides of the block. So in your example, the smaller buildings might be only 2/3rds of their depth, forming courtyards in the center of the block that aren't exclusively part of any one building. I'm not really sure why it happened that way, historically, that they didn't build as deep back into the block as they could. Perhaps because the apartments were small and they could get two across a hall if the rear apartment had a window to at least some air. (Having lived in one of these rear ones in Prague for a little while, I can attest that it's not a window you want to open - the air is mostly full of pigeon feathers and excrement). The way you have them formed, though, seems to point to an obvious algorithm that would divide building fronts into tall rectangles and stitch them together. I wonder since you already have all those nice street splines, maybe they could be applied to the building faces and rooftops as well.
