Thank you everyone for the really helpful input. You really have mostly put me off village life unless I can find one large enough to cover the other bases. Am especially concerned about the teens not being able to get themselves around independently when the time comes
hh19, I am busy looking up properties on RM that I like, and will then whittle it down after more in-depth research on each area - factoring in commute to London but bearing in mind that that job may end (the nature of his work) and DH can look at other jobs closer to home, and knowing where the key hubs of his industry are. Though he has lots of options in London so that is important too. I also want to be able to go in to London with the kids once a month at least, and not feel like it's a massive long trip outwith peak traintimes (i.e. irregular, long and calling at all the stops, once rush hour is over).
I am open to being told a better way of doing things though! We are flexible on area within Surrey/Kent/Sussex or just outside - depending on commuting times to London. I'd love a village with good facilities if I can find one, or else a small town, or a suburb of a town, with a pretty high street we can walk to, not reliant on the car all the time, and lots of family-orientated community activities so the kids can make friends quickly and feel involved. At the same time, both are quite happy being homebirds when the mood strikes, so I'd like a good home space with a big enough garden that we don't have to go to a park if they want a run around and to hug some trees, with big enough rooms so they can hang out comfortably and not feel cramped. Primary schools are actually low on our list as we home educate for now, and I don't see that changing for this stage, but I want to factor in secondary schools so we have that option later. Also as home edders, that does mean we need extra space for them to work at home - a comfortable area for both of them. And also as such, they require great access to the extra-curricular activites like they currently do - trampolining, gymnastics, dance, football, dive club, singing club etc.
I don't know if my requirements are too vague or too much!
