I suggest you read retail guru Bill Grimsey’s three reports on the High Street; with nigh on 50 years in retail starting in a market and finishing as boss of Tesco and also the biggest retailer in the Far East, he knows what he is talking about. High streets will have to change massively, many Town Centre shops will be converted to residential, it’s already happening, many big names will probably go exclusively online, many High Streets already have virtually no shops - see Baldock, Herts. Where there is a very large Tesco in a former lingerie factory at one end of the Street and a small Londis or Mace or something at the other and nothing in between but estate agents, flats, offices and pubs.
town centres will need small, independent quality retailers to offer something different and quirky to create USPs to attract people to come, otherwise there will be no need for people to go there. Sadly, I can’t see model shops being a major force.
Many out of town shopping malls like the Metro Centre in Gateshead are now in trouble because they have lost so many stores, particularly the large ones like Debenham’s (huge in the Metro Centre), BHS, John Lewis, Boots, and The House of Fraser (again, both huge in the Metro Centre) It was happening before Covid which has made it much worse.
