Enclosed spaces provide for more concentration levels as the amount of visual and sound disturbances are minimised. You could set your own lighting levels as well. I think it comes down to the floor space requirement which comes at a premium. One can have an open office space of 6ft x 6ft and still not feel claustrophobic. But for a dedicated office with closed doors, you may need at least 8ft x 8ft of space, if not more. Almost double the floor space..
Duh, nobody doesn’t understand that open plans are cheaper. Our point is that it’s a false economy to save a few hundred bucks a month on rent, at the expense of a few thousand bucks of productivity (and the employees’ sanity).
Companies do dumb stuff like this routinely.
When I worked in TV, I could replace 27" Broadcast monitor CRTs at $1200 "a pop", several times a year, without them turning a hair,
& "the biggie", -----------replace the Final tube in an NEC TV Transmitter, at $12,000!
*I had to get permission to spend Petty Cash, though!
*The PA tube price sounds horrendous, & there were cheaper suppliers, but the Boss ruled them out, due to longevity problems.
The ones we used lasted for many thousands of hours.
