Personally I think it’s going to be a bit of a mix - for the foreseeable, anyway. Generally we seem to be moving towards 2 or 3 days in the office, focused as much as possible on real-world interaction, and the balance working remotely. There’s certainly no appetite that I can see for a return to full-time commuting, but similarly no appetite for home working only, forever. I’m quite happy with that, I’ve been in the same bit of London for over 20 years and I like it here; by the same token I’d be lying if I said I missed the joys of the Jubilee Line on a humid Monday morning!
Obviously the above is also contingent on our clients’ desires, in the main they seem to be looking at the same sort of hybrid approach but some will no doubt go the three-line-whip route to full time office work, depending on their culture.
As for longer distance commuting, I once had a colleague who commuted to the City from Rugby every day, which he professed to find entirely satisfactory but would’ve driven me absolutely hatstand. Horses for courses, innit.
