I'm pretty sure this describes exactly what went wrong for me. I worked in an open plan office for 6 years and then for a variety of reasons fled for a WFH arrangement for 2 years with the same company (under the guise of moving to a different city where an office didn't exist). I think in the end I liked being in the office much more than WFH but that what it really represented was a private workspace for the deep no-interuption work. However, I missed being near my co-workers so much that I eventually gave up on it. There's no doubt that I would have never left had I had a private office at the main office instead.
