We're buying a cottage which doesn't have the layout we need upstairs (ideally need 3 double bedrooms). It looks like it was originally 2 doubles and the end single (it can fit a double bed). The only option I can see is to take out the partition wall between the middle two bedrooms, but that'll give two huge bedrooms and one single - can anyone see any other option? I think the chimney stops anything being done with that wall.

If you already have an office then in my suggestion I'd use the small room as a reading nook or craft room - some sort of hobby space.

Why have they done that?

If you can't lose the fireplace, or swap the bathroom around, the only option seems to be changing the wonky wall to a straight one. But that only gains you a foot in the smaller room. That would only be worth the hassle if an easily moveable partition wall.

I really like @HoHoHoliday suggestion. If you do not want or need that 3rd smaller room, you can leave it open, creating a gorgeous landing space where you can put sitting, bookshelves, etc. It has a window so would be a lovely shared space. I love big landings and random dens in a house.
