Hedge height
 

OK - steps are being taken to limit the height of hedges and rightly so.
What about the following situation?

Towards the end of my lane there are a couple of big (massive) detached
houses which back onto fields. They have tall (20ft) very well maintained
leylandii hedges between them and the fields - no problem at the moment.
But .. new houses are now being built on the fields (awful). Can they be
forced to reduce the height of their hedges even though they were there
before the new houses and even though anyone buying one of the new houses
will be aware of the hedges before buying?

Just wondered - doesn't affect me personally.
