We currently have a three foot fence between us and our neighbours. They are not willing to extend it up to six feet , which , as it is their fence, is fair enough. However ,we do feel the need for a little more privacy than the current fence affords us , especially as we are very overlooked by additional properties to their side , and , having two young children to consider, privacy and security is important to us.We don't particularly want to stick a six foot fence up on our side either ; but would rather look at a little strategic yet fairly innoffensive planting to create a privacy screen. We don't really want to do the whole leylandi thing (although it would be super effective on the privacy front) - as we worry about it getting too full on and hard to keep control of (i know that these grow so quickly).Also , we have to be careful on the roots front as the screen is very close to both our kitchen and theirs (plus obviously , house foundations).Does anyone have any suggestions as to what may work ?? Ideally something that is under six feet. Also , does anyone know if nighbours can complain about losing sunlight as a result (even if we keep it under six feet ?) Any help / ideas greatly appreciated -thanks in advance!
