It is interesting how the fortunes of the people and houses change over time, frequently starting as upper middle class then through the decades until we often find the house divided multiple times to accommodate poor working class, then as we get to our century, the house is once again gentrified and occupied by the well off.
Brighton has loads of such houses. In fact my DH childhood home was one such, his g grandparents were like those in the tv programme - cobblers, which grandparents inherited, but did not make a go of the business, gradually the whole area became affordable houses for working class folk, but now they have once again been gentrified and are mind-blowingly expensive considering their size etc.
