Our neighbours garage forms part of our boundary and can be seen from our garden; fine, it's lovely red brick. But they extended their garage with ugly grey breezeblock and that's a large part of our garden boundary (2.8mx2.8m). After 4 years I'm fed up with looking at it in summer when we're out there a lot, so what can I do to cover/screen it?
I was going to put trellis up it but have read that's a no no as it's not our wall. We've bought honeysuckle plants but need some way of helping them climb. We could erect fence posts and trellis on our side, but it's patio and would be a pain to sink fence posts.
The neighbours actually have a huge old wisteria plant which hangs over this wall considerably - so I wondered about an arbour seat or something to prop up the wisteria and partly cover the wall? Or something else entirely?!
