I really feel for you. Once it starts getting on your nerves, it’s really hard to deal with isn’t it.
No council will respond to this either. As it’s children living their lives.
I’m in a similar situation and quite surrounded by noisy kids.
There are parks and playgrounds in walking distance but understand why parents don’t let their kids go independently as crazy stuff happens.
My adjoining neighbours rent the house and their landlord is rubbish. I have put a fence up on their side for privacy but the kids just kick a ball against it constantly.
Also as my neighbouring house has a garden that nobody maintains, their little friends have been coming over all summer and just running round screaming and kicking a football etc
I think in the morning the little boys friends come round to let rip and in the afternoon it’s the daughter’s friends. It’s awful. So it’s non stop.
I have no idea how to stop it, apart from stay indoors with windows closed and go out just to get away from it.
I’m sure when schools re open it will stop but I work in a school so there’s no escape!!
Anybody who has suggested to move away and live in the country whatever that means is not very helpful either.. You still have noisy kids plus ones on off road bikes etc.
Good luck!
