I have a small garden I'm trying to turn from patch of lawn & patio into a fully paved & planted elegant entertaining space
. I'm looking to fix a horizontal panel fence along the side adjoining my neighbour and will add some gentle climbers but the fence I want to use is 6ft 6 (so within the permitted height) but this is 6" higher than the existing fence which I'm guessing could be quite unpopular with my neighbour - we both have big patio doors right next to the fence so will be very visible from the house.
What's the protocol here - inform them first and hope they don't object or just get on with it? And will it look really awful for them having a higher fence poking out the top of their existing fence? If it makes any difference they have the 'good' side of the fence which is another reason for wanting to cover it.
