Thanks everyone who has taken the time to reply. I think I am a bit similar to the other OP who is posting about not being able to find the right place for her and her family in that I think I would like to be out of London now we have kids but in a place that has character, so Folkestone, Faversham, Lewes, Woodbridge, Hastings, Rye - places like that really appeal to me but they don't work because they are all too far for a daily commute and a husband that works all the time! Towns that are not too big, have community feel, a bit arty.
We had a chat and we both agree that we don't want that life where I live far out and DH lives in London and never sees us. So yes, I've been searching for a place that doesn't exist really - somewhere within an hour door to door commute that is a bit like any of the above places! And not too far from my parents. I don't want to be anymore than 2hr from them.
Which leaves us in the commuter belt or back in London. All the villagey London bits sound good on paper - Barnes I love, but I agree I'm not it would actually suit me that well, plus the plane noise I think is a no and wrong side for my parents, but actually I think Barnes would be better for us than Richmond proper as it's feels very green and less busy and Richmond is easy to access there anyway. I think we've now ruled out Richmond/Kew etc as wrong side for parents/commute/extremely expensive/plane noise, though the schools seem very good and on paper it would be the best place in London to raise kids I think, safe, green, river, parks etc.
Interested in Chiswick though I think it also may feel too busy now with the big roads cutting through. And not that easy to get up to East Anglia (though easier than Richmond).
Going to look back at around Crouch End, Highgate, Tufnell Park way and up to Winchmore Hill too to see how I feel further out north. Definitely going to revisit Wanstead for east suburbs/access to parents/good greenery and Dulwich as another London village.
What we may end up doing I suspect is staying put, getting a tiny flat in central London, I go up a bit more for work/weekends to see friends and I start trying to put down roots, find some like-minded mates and enjoy the greenery and peace around here.
