Good monring,

I’m starting my garden kitchen build at the weekend and as part of the build I need to build a retaining wall, the wall will create the literal wall on 2 sides of the kitchen so will need to be about 2.4 meters tall, but it will only be retaining about 1.5 meters of earth at the highest point.

I was planning to use breezeblocks, and then render it and paint, but this seems very labour intensive and I've never laid a wall before, let alone rendered anything.

So I've also considered doing a sleeper wall, putting 3 meter sleepers vertically, concreted in the ground, and tied together near the top with a metal band. This would also give a nice "rustic" finish and I personally would prefer this finish to a rendered wall.

I would put some landscaping fabric up against the back of the sleepers and then a layer of gravel for drainage.

Any thoughts on either design, or any other ideas?

Thanks

Ok, you are all kind of echoing my concerns with the sleepers.

I'll probally stick to block wall then, but a good idea to timber clad, rather than render, I may look into that

Thanks smile

Forget the longevity, sleepers won't stand the weight without snapping. Plus an embedded retaining wall needs to be two thirds in the ground and 1 third out.

At 1.5m high you really should get the thing deigned, not just stab a guess and start building, but for a masonry gravity wall a rough rule of thumb is to make it 1/3 the thickness of the retained height, ie 500mm thick for yours. That can be by laying a front face and then pouring concrete behind.
1.5 meters was a genourous guess, it's less than that, and besides the slope is already "self supporting" so it's only the bottom section of the slope I am chipping away.

Here is my comprehensive scientifically accurate diagram:

As this is going to end up as an "internal wall" I dont really want wire and stones on show.

Someone above mentioned timber faced Gabions, cant seem to find anything on them online.....

the retaining wall is going to be the extension wall too?
that needs a lot more design than offered here,
Garden kitchen with no proper roof, a bit like this, so damp etc doesn't matter, doesn't have to be perfect!
