Advice - Fitting trellis to top of garden wall

Dave_6

Hi,

Need some advice with fitting trellis.

This is my garden below, as you can see I have bungalows behind me and the garden wall isn't quite high enough to give full privacy.
My house ground floor is a foot higher than where this picture was taken from so we can currently see into eachothers properties.

I'd like to add the below, 30cm high trellis along the wall.

The wall is double brick thickness and is mine, overall height will remain below the legal height etc.
Wall is 15 years old.

I seem to have 3 options but don't know which to go for.....

Option 1. Lay a 10cm x 10cm timber batten/fence post across the top of the wall and drill that into the top of the wall.
Then attach trellis to the front side of the batten

Option 2. Attach a batten horizontally to the side of the wall facing me. It would only be attached to that top layer of bricks though due to the lip that exists on the wall.
Trellis would then be attached to that batten.

Option 3. Attach verticle battens going down the wall, these will go down the wall approx 30cm, and above the wall 30cm. Trellis will then attach to the top 30cm of the battens.





Trellis 30cm high




Personally I think option 1 might be best, but not sure if it's a good idea basically attaching a wooden fence post to the top of the wall horizontally

My OH has just done this Dave, replacing some old, low fence panels that were atop the wall which blew down in the storms last week. Our wall is concrete, and he has attached vertical supports to the wall to hold the trellis, almost like mini fence posts. They are screwed to the wall our side and go about half way down, and the whole height of the trellis. It looks very neat and holds the trellis perfectly rigid, but as he used to teach this kind of stuff I wouldn't expect less.

I am not sure of the technical details I am afraid and he is not around to ask just at the moment. However if you have any specific questions I can do later when he comes in.

As DawnW says the best way is to fix posts vertically to your side of the wall sticking up by 30cm or a little more and then fix the trellis either to the front ie your side or the back of the posts. I think that it would look better facing you thus hiding the tops of the posts. As the wall has a drip tile sticking out of the brickwork you will have to notch the posts to sit over this, also the posts will need caps to prevent rot. Your other two options in my view are no goers as to fix the trellis directly to the top of the brickwork wouldn't give a rigid enough fixing, and fixing only to the capping bricks as in option 2 would weaken the top course of bricks and lead to damaging the wall.

Hi,
Thanks for the replies.

Still looking into various options. Was hoping to avoid the posts down my side of the wall but understand it might be the best option.

Another is maybe some builders merchant brackets.....
These would be more discreet and could be placed side by side with an adjoining wooden face screwed in to add strength.
The trellis could then be screwed into that wooden block face.
They are 15cm in height, if the wooden face was say 20cm in height that would give a fair bit of support.
