I'm in a rental and nothing has been updated, we have lived here a decade and a half and nothings been done in that time but nothing was new then.
Our bathroom must be ancient with its dark wood, paneling, huge corner bath, old giant feature tiles of scantly clad women in windows pouring urns of liquid, gold taps etc... got to at least be from the 70s. It is literally rotting and rusting away in real time, the floor is collapsing, the pipes leak from rust and nothing works but landlord wont replace it.
Kitchen quite old with its heavy orange wood and wood paneling ceiling, so old some of it (like the subway tiled parts) have come back into fashion. Possibly same ages as bathroom as that area of the house was built at the same time. Both where probably top of the line expensive at the time but is destroyed purely through age.
The wallpaper in the hallway is the exact same one my childhood house had in the 90s, I remember the decorators hanging it so circa 1995-ish. The personal nostalgia is part of why I liked the house.
Built in wardrobes classic pre my lifetime. Had the same ones in our childhood home which where there long before I even existed. From rightmove old listing it seems most houses on the street had the same ones but they certainly can't be Victorian so everyone must have choose to add the same ones later.
Living room was probably the most modern decorated room in the house, its magnolia with a feature wall straight out of the 2000s and dark laminate.
