Building wall within boundary

gazman101

My neighbour recently approached me regarding raising the block boundary wall between our properties to increase the privacy. I sought advice from a builder and was told that the wall would become unstable if it were to be raised due to the fact its currently at its max height (almost 6ft) for the size block we have and also a crack that has developed due to roots from a nearby tree. I informed my neighbor about this and we discussed alternatives such as a trellis or lattice that could be placed next to the wall.

My question is are there any height restrictions for a wall/fence if its inside of the boundary? I've read that the boundary wall itself can be a maximum of 2m in height without planning permission.

Cheers,

Max boundary wall to the rear is 2m. Anything higher requires planning.

But you could attach trellis to this without an issue, yeah? And if you want full privacy grow something nice up the trellis..

Technically no would be my interpretation but I’m
Open to counter arguments. (Assuming trellis is a timber structure to support the plant growth)

I agree with KC re the trellis being a bit edge case.
What has a better chance of working is the green mesh used for windbreaks, which you can always plant against.
the attached, out front, past muster with FCC, the block wall is 4 feet

How close is the tree?

I'm no engineer but the crack suggests the wall has inadequate foundations, because horizontal tree roots don't go very deep and won't go through walls, so must have gone underneath a shallow foundation.

When I had a 6ft wall priced it had something like 300mm solid block below ground plus aggregate.

Anyway, it's not going to magically get more stable over time. Attaching anything solid to the top of a weak wall is going to generate wind load that may finish it off.

edit: actually it was a 2m stone wall over a 3ft wide and 3ft deep trench partially filled with concrete and then blocks to ground level before the stone started.
