It's a difficult one as you will need to build something between the fence and the raised bed. Possibly you could dig in 2 timber fence posts 75mm x 50mm by height required. Set them in the ground with concrete and then nail tantalised timber panels, A bit easier than breeze blocks but still requires some practical experience to do.
Post will cost £5 each
Timber panels will depend on length but a 6' lenght timber gravel board 150mm wide will cost u about £4
Post set £5 per post
