Garden boundary wall and fence

[SouthCoastDIYer]

Hi, new to here but have been looking through past posts and found lots of helpful answers for our upcoming project.

mine we can’t find; we have planning permission to erect a 9ft boundary to our garden - which faces the main road.

we intend to do a 3ft wall with 6ft timber fence above.

we intend to use concrete posts, 11ft in length.

Can we build the wall from 100 or 140mm block in line / between the concrete posts, and then tie a block wall face to the outer side (road side) of this? Or, do the fence posts need to sit independent of the wall? (I.e not with the blockwork inbetween)?

thanks in advance...

Fence posts will deflect quite a bit more than a block wall. Block walls don't deflect well - they tend to crack. I recently reported on a 900mm 215mm brick wall that had a 900mm fence on top. It blew over.
I would advise keeping the fence separate to the wall. You could build in-line but leave an expansion joint and don't tie the wall to the posts.

Thanks, that’s exactly what I was concerned might happen! Just trying to come up with a way of not needing to build the 3ft wall and then have the fence panels sat on another 3ft of concrete gravel boards but looks like it might be the right thing to do...

Generally speaking, fence height is restricted to 2m.
