Floating Bench Garden Wall

[karlitob1983]

Hi all

Appreciate your advice on the following.

As part of our garden design, I’m planning to build an ‘L-shaped’ garden wall with an ‘L-shaped’ floating bench attached.

I’m thinking of going with a 4’ block on flat wall (3m x 3.7m ‘L-shape), 900mm tall with the bench somewhere at 450mm. Can anyone advise the best way to support the bench please.

I’ve seen a few suggestions - box steel through a planter wall to the far side of the wall (not applicable here as not building planters); an ‘L-bracket’ but the fixings are visible.

My main concern is the structural integrity of the wall. Would really appreciate your comments. Thank you.

What material are you using for the bench?

Wood?

you probably need a steel post of some sort cast into the foundation -with a bracket welded to it to come out just under the seat.

with block on flat construction maybe you could core drill out for each post as you build -the horizontal brackets would need attaching once you got the blockwork to the height needed.

or maybe posts just behind the wall coming up and brackets weld to them going through the wall -that would only work if the other side of the wall is not important visually

Yes, wood. Thank you.

is core drilling just messing about do you think?

I was hoping I could get a t shaped bracket. One part of the t goes into the mortar, the other supports the bench and the straight piece hard up against the wall itself.

I did see what you suggest about steel at the back but mine would be seen.


Any other options? I’m not married to block on flat but don’t want planters.

how much wall is there above the bench? I.e.
Is the wall a backrest? Is it heavy enough to counterbalance the bench + occupiers?
You could just insert strips of steel sticking out of the wall at intervals.

Thanks for that.

I’m planning a 900mm wall, and the seating at 450mm. I spotted the strips of steel idea. Any idea how I could confirm the structural integral integrity? Some online calculator.
