Subjectively, most UK cities feel less dense than many continental cities, with less apartment living and more urban streets with two story terraced houses. Could tell a similar story about that.
UK laissez-faire local government combined with tribal politics making the ruling party incentivized to starve those local governments of funding - especially transfer funding when Tories are in power and Tory local government is usually restricted to rich areas not needing transfer funding - more material for storytelling.
IMO the UK political culture is toxic, education is particularly poor. Everything is centered on London and yet all the elite live outside in the green belt, while crime driven by inequality is rising and police numbers are continually cut, and legal aid is also being cut, leading to mistrials and slow cases due to self representation, and free movement is attacked by all sides.
I'm looking for the exit. This place is sick. The next domino will be something even more extreme, and it's chance whether it's left or right extremism.
