It always surprises me when huge new office building are constructed in the city centre given the inexorable march towards working from home. I work in IT/Financial Services and we've been on a 60/40 WFH policy for years now, as is the case for many of the roles across the sector.
Currently the 95% of the organisation (2000 odd) is working from home 100% compared to 25% of it 3 days a week, the company was supposedly looking for additional accommodation as our current desk space was becoming over subscribed but I can see them reviewing this decision after all this.
Speaking as a city centre dweller I'd much prefer construction to switch to residential away from office as I want to increase the population density (not right now, they can all stay the f**k away until the crisis is over

). Reducing the number of commuters into the city would be fantastic side affect of all this.
Going into the office 2/3 days a week suits me but if everyone did it what a difference it would make on the roads and packed trains.
