I had a company throughout the 1990's that used to renovate (refurbs and renovations) very similar city centre office blocks to this, here in the UK....I always enjoyed working on them and being in those spaces...I had a great crew working for me, and still miss those times.
I imagine the perceived tranquility of the above photo was soon swallowed up when deadlines had to be met....But, I find this image very calming...it's a great space.
Office area, right at the backend of the computer-free era..1976-ish, or thereabouts.
