There are some particularly egregious versions visible from the station at Reading, which I think might be Owen H's home town:
Owen's from Southampton originally, he disects the city in the first chapter of A Guide to the New Ruins of Great Britain but you are right about Reading having loads of great examples around the vicinity of the station of the sort of provincial PoMo stuff which the 1980s/90s supermarket architecture that Luka was alluding to at the beginning of the thread is the most ubiquitous example of. Reading also features in Patrick Keiller's Robinson in Space. I can't remember the exact point he makes about it but it's always seemed to me to be a kind of portal through which all activity between London and the tech industries of the M4 corridor is funnelled through.
