Hello all I need some advice regarding building walls, specifically building a garden wall
It has been many years since I have tackled anything like this so I need somebody to verify/confirmed/shoot down in flames my plan
Anyway, enough waffle....
In my garden there is a terrace that I want to extend out into the, currently turfed, garden:
In order to acheive this I need to build a wall to retain the fill required to bring the "terrace extension" to the same level as the current terrace. The position of this wall is shown in the pic by the white string line (total length = 4800mm + 2400mm (7200mm), total height 1000mm)
I intend to dig a 800mm deep, 400mm wide foundation down onto the clay layer under the garden. This will be concrete back filled to a depth of 700mm. The first course will sit on this foundation.
The wall itself will be double skin, the inner skin will be simple breeze block, the outer skin will be dress stone (you can see the sort of dress stone on the wall that leads out on the left). Both skins will be bolt tied to existing walls at either end.
Once the wall is in place the "swimming pool" it creates will be filled with hardcore and then "her indoors" has to decide was fancy paving she wants
So that the plan, which at the moment doesnt include any drainage which is one thing I am not sure if it needs or not.
What have I missed here?
The reason I am doing this myself? Well all quotes I have had have been around 3k, this is due to the volume of donkey work that needs to be done (e.g. foundations have to be dug and filled by hand and many tonnes of back fill has to be hand carried in as there is no way to get any machinery into the garden)
Having said all this, plan B is to do the foundation work myself, get somebody in to build and top the wall and then fill it myself
Then there is always plan C, which is to only build the wall parallel to the terrace and then used bison beams to bridge across to the terrace, infil and screeded. This then leaves a void that I can use for storage
