I completely understand your issue, as we have much the same...we own a bungalow on a private rd with similar but smaller on each side. Three years ago one was bought by 2 20 somethings, and 2 children one 5, one 2. Into a 2 bed home, they now have 4 children in a 3 bed. The parents appear to think screaming at the children is what control and discipline is, so I suppose I shouldn't be surprised that the children follow suit. At no point have they stopped building, as it is a self build extension, so permanent building noise every evening, weekend and bank holidays. On top of this - the two older children 'play's and scream from 8-8 weekends, and outside school hours likewise. They have a skateboard, scooter ramp 8ft high, which rumbles all the way up and all the way down for hours on end, plus the didn't ask for planning. We have lost our quiet, our privacy, and our view...but we are told to be understanding. Earplugs, cotton wool, keep your windows shut, upgrade your windows...Sorry, but why? We have been patient but we are at the point of considering losing our dream home, just to escape the constant noise. I'm a Grandma, but I have never heard my young grandson make anything like this level of noise, nor his friends.
I know children must play, yes it is better to be outside than in or online - but surely teaching children care and consideration for their neighbours should be part of raising a child. I'm only 55 but obviously my ideas on manners and consideration are hopelessly outdated
