Is it better to have a big living room and a small bedroom or a small living room and a big bedroom?

Good design of separating the living room from the small bedroom: It is possible to make a new division of the living room area, which needs to be negotiated with the designer, and the designer is mainly responsible for it, but I suggest that you treat that room as a simple room, mainly as a part of the reception area, that is, the walls and doors can be separated, and it is not an independent area.
