The reflection of the evergreens (?) in the glass panes adds another layer of texture. Also like the dead leaf amongst the new growth at the top of the plant.
This is my take on it. Hope you don't mind Anti. If you want me to remove it, I will.
I felt that the peeling paint and old look of the windows could be a bit more pronounced. So, what I did was defogged the image with unsharp mask at 40, 60, 1. Then boosted the overall saturation to +30, and sharpened at 150, 0.3, 0. But I also think the original is quite good.
