Yep, 30 in my boys' classes too. That's the maximum allowed class size for primary school and it seems that any half decent school is over subscribed now. I was worried about it when DS1 started school but it hasn't affected him at all and the school still manages to keep a small/village feel about it. I find that many of the schools with lower numbers in a year group merge year groups so there ends up being as many children to a class anyway.
rainbowflower - just noticed we're in neighbouring counties :D
nbp - there are many houses like the one you describe here! We have a chimney (but we haven't used it yet!) but no picket fence, just hedgerow. Lots of the houses are much, much older than ours and many are thatched - again, not ours!
