My garden is 40ft long, terraced down from the bungalow. This terracing continues in the very short garden beyond, where the house bedroom windows are level with my kitchen. Between us is an 11ft high hedge to give privacy both ways. The hedge has become a nightmare to maintain, and age and common sense say it must go. But what do I replace it with? I am thinking of a 6ft fence topped with 3ft trellis and climbers, but any fence over 2m high is illegal without planning permission. Would that matter if both parties want it? Or trees? Tall shrubs? (Both would have to be columnar). Next door have 12ft leylandii, but NO! Has anyone any ideas?
