The Story might not be obvious unless you are looking out for it Letitia. All properties have a history but they are probably all presented as they were at a particular phase. This includes the rooms they have on public display as in larger properties most may be closed. It will probably also include the choice of art works on display.
Classic example is the one nearest to me (not the one I volunteer in) in which the rooms that are open show the property pretty much how it was in the early 20th C. The last owner's study, frozen in time, with his half a dozen desks each with piles of papers relating to one of his hobbies. The focus is on the family and the reception rooms not the whole life of the house - the kitchen areas have been converted into shops, restaurant etc and the servants bedrooms are not part of the offering. There was a previous aristocratic owner who was much more interesting and colourful. We'd have probably called him a drag queen today - obsessed with dressing up and performing. He'd have been happy in the age of glam rock. A lavish spender who squandered the family's fortunes and died in his 30s. How much more entertaining would it be to see his costumes and the chapel that he converted into a theatre (rather than a messy study). Alas no. Rumour has it that the family, ashamed by their cousin's disgraceful behaviour, don't have much of his stuff, just a few photos. (But it may also be that they are still around and having some influence on how the family is presented. ) Anyway the alternative "story" is consigned to few photos in a back corridor.
Another one I know, Upton House, is presented as for a 1920s house party, when it was owned by the chap who owned Shell Oil. So their stunning 1920s jade green and silver bathroom is shown off in context
