I am not very used to create monochrome images, but this archticture is more or less forcing me to try it

Good thing about black-n-white is you don’t have to worry about color… 
After grayscaling, I rotated it a bit to make the nearest corner vertical, then an aggressive tone curve that turned out to just be an exposure boost, that is, straight-line, to get some contrast going:
I think it’s a great monochrome subject, and a fun composition.

I preferred colourful…
More focus on the only open window, “gradient-ed” the sky. Sharpened to the max.

First pass. My edit is a little cliche, but serviceable as a rough draft. I feel like there is a lot you might be able to do with crops and dodging and burning.

My edit in DT 5.6. I used color calibration module for monochrome conversion.

That is more the look that I wanted to achieve… bright sky and many details in the blinds. I did not get that, despite also working with colour calibration. So I will have to invistage your .xmp
