It appears that we have forgotten that even as little as 100 years ago most people worked from home. Farmers worked at home, Shopkeepers, Innkeepers and Tradesmen lived at their premises. My Grandfather, a Stockbroker, worked from home on days when he was not at the Exchange. A Great-Uncle who owned a bronze foundry (his best known product stands in New York harbour) lived in his foundry complex. My husband, a lawyer, had a home office. So working at home is not precisely the novelty it seems today.
To think that London, or anywhere else for that matter, does not belong to any one demographic
