A lot of postwar development in the UK has been clustered around disused WWII bases. There are several government research/nuclear establishments, and numerous industrial and commercial sites. Several airfields have also been converted to solar farms now.
I think this has been positive as a way of unlocking land for things that need space. So much of England is "precious" both in terms of value and how it is protected. Having a place to build and rebuild grotty factory units is very helpful.
I live near a site that started as an arm's depot. About twenty years ago it started to be leased as small units to startups. Many biotech spin-off companies that needed adaptable space moved in. Now it is full of large biotech labs and distribution centers. Soon there will be large data centres. There are a couple of nuclear research sites on old airfields close by which also host a space cluster.
