Just musing this idea!
Lockdown has really shown how much noisy neighbours impact on quality of life, both inside our houses and in our gardens.
Would it be possible to plan for quiet areas in new developments, where covenants are drawn up to prohibit certain behaviours e.g. amplified music/radios/TVs in gardens?
I guess there would be loads of practical issues around what would constitute reasonable noise when it comes to children playing etc. But if there was some way to make it workable I would absolutely sign up!
