"but now I’m not going to be going back into the office full time I’m much more open to living somewhere with a bit of a drive to the station if it’s only going to be for two days a week."
My very personal view is that all this hype about a revolution coming, the cities are dead, everyone will work from home etc is just hype. Remote working will definitely increase but I don't think we will transition to working from home 90%, for a number of reasons: from managers wanting to see their minions to get an illusion of control, all the way to the fact that too many jobs require constant interaction, to the fact that some jobs require specific software or network access which means working from home is inefficient. If you have 10 years of experience you can probably work from home just fine, but how do you train juniors graduates etc?
Even if we ended up working from home 50% of the time I would not want to live in the middle of nowhere and spend crazy amounts of time commuting; if it were only 3 days per month I'd think about it, but I very much doubt it will be.
So for me the best compromise remain, if you can afford it and I get it not everyone can, those zone2/3 areas (or equivalent in other cities) where you can still buy a terraced house or a maisonette or a flat with a little bit of outside space BUT getting to a central London station takes a 15-20 minute tube or train journey, which probably means 30 to 45 minutes door to door.
Of course that's just me and loads of people will have different opinions and preferences.
