You'll be fine bascom49, good advice from markbarendt so I don't need to add...
If you had framed the shot where the main interest was inside the back room behind the wall with graffiti... Then you might be looking at a scene with greater range that might need compensating developing. There are some good threads about that.
But I don't think, with the shot as you show, that there is anything in that far-back room that you care to reveal.
So treat it normally and you should be fine.
If you find that the shot at 1/25 second is a "better" negative, I would recommend lowering your EI to agree with what gave you a good negative.
