You have my deepest sympathies, or rather empathies, as we too seem to have neighbours who live by the 'Gospel of Anti-social f@#kwits'. I have never known one family have so many anti-social behaviours - barking dogs, excessive DIY, radios and TVs through the wall, dope smoke drifting dow the street, abusive, and yes horrendous grandchildren screaming in the garden for hours. I have 2 lively boys, one with ASD and they don't make anywhere close to the noise these kids make. And yes, its the irritating adults encouraging noise that is the worst bit about it. They don't come round as much, but a few years back it would be every weekend, hours of screaming both days. All the other neighbours doors and windows shut all summer along the back of our row. Horrendous.
Since money is no longer the badge of behaviour, I think some sort of personality test is needed when people are viewing houses:
Fairly quiet, considerate of others, noises within usual living - you can live anywhere
A bit noisy, maybe lots of kids or dogs, prone to parties - semi detached or detached for you
A complete f£%kwit who doesn't give a toss about anyone? - Butlins for you, along with all the others like you, with a big soundproof glass dome around you, as far away from other humans as possible!
