In common with most other cities around, the inner city used used not to be the exclusive preserve of finance houses and coffee shops. Instead, they were a hive of manufacturing, mostly smaller workshops and businesses. Great Portland Street, for example, had the fabric trade, Hatton Garden, jewellery. The East End city outskirts was where a lot of small businesses started, these workshops built in the sixties would likely have been chock full. Times change, don't they?
