I can see large offices being a thing of the past, so if I owned any of these I would be selling them sharpish before the market dies, just like the high street is. It's going to happen, people may deny it or fight it, but they would be better off embracing technology faster in the most part.
I can see the potential for a hot desk office mind, where people all just turn up to a standard office, and work from there one day every two weeks, or even having a day in a coffee shop. Or multiple companies sharing a commercial space and booking office or meeting time etc.
Paperwork should no longer exist already, but slow uptakers will get forced to change by online accounts systems, making tax digital, cashless etc, all of these changes make offices less necessary. Teams and zoom will get better, filling cabinets will vanish.
Even construction, which is old school, it's pretty much 100% digitised invoices now and online payments, can't remember the last time I sent a paper invoice, or even received one and don't even know where the cheque or paying in book is, I've not seen either of them for years
Site visits and meetings in offices are down about 90% for me, and productivity is up
Good news for the environment too, this should help with green targets.
