I live in a multi family home, which I own. It was once a single family home. My apartment is made up of the second floor of the building, for which I have included a not-to-scale floor plan below. The hallway marked with (1) is unusually narrow, and has plumbing and electrical pipes on the right side of it further narrowing the useful space. This poses a challenge for moving bulky items in and out of the living room (marked with (2)).
Right now, I have a couch located in the bedroom (marked with (0)) and I want it in the living room (marked with (2)). I tried to move it through the only hallway (marked with (1)) to the living room, but it would not fit. If I were to do extensive plumbing and roof work (one of the pipes is a vent), it might just barely fit. I have also considered adding a door between the two bedrooms, since the route from the top bedroom to the living room and kitchen does not require any unusually narrow passages (the floor plan is not to scale), but I have reason to believe that this wall is structural so that is going to be an expensive option since due to my personal skill profile I'd need a professional to be involved. I could handle it in a non-structural wall, I think.
Are there any other ways to do this? I have considered using windows to move bulky items in and out, but as this is on the second floor, that seems hard: I'd need a stable and decently large platform to maneuver bulky items through the windows, and I don't know of any affordable way to obtain that.
