A deeper perpective...
Undoubtedly working from has shown to be better, hardly a study disagrees with it, My workplace requires managers to allow one day from home, up to a maximum of four, though a manager can decide for this to be zero, which was the case, until my new one decided he'd like me two days a week, which are not quite full days either. Problem is that not all others are in on the same days, so out of the few who would be in our area, typically it's just two. Now in the old days, I worked for large consultancies, you could tap an expert on the shoulder and they'd save you hours of time, and you could do the same for someone else. I miss that, but then again they made me commute thousands of miles every year. Now my commute is a bike ride of less than half an hour, and the team, within a huge organisation, is small and doesn't have that many other experts anyway. Yes, I do get less work done on-site. My story, is probably not like anyone else's, but probably has parallels.
True, big landlords want their tenants back, but the support industry, the cafe's the shops around the office, now have a reduced income and may need fewer people. Then again home shopping might increase and shift the jobs to local shops and online warehouses (that are being automated more and more, but let's not talk about automation here).
Another angle, Covid-19 gave a unique opportunity to study mass home working and the idea of BMI (not weight index, basic minimum income). I digress here a little, it was squandered by political hubris though, simply giving everyone with an NI number £1k a month, no messing around with giving it through companies and business loans, near zero extra admin costs, but no, they had to enrich/look after their wealthy voter base with £2.5k payments, whilst those on the other end ended up with less than £400 a month, and the business loan fund was looted like an ATM throwing out money.
