Earth retention when raising lawn

Hi, I have an 18m lawn which slopes gently towards the house for the 10m nearest to the house. It has a 3 foot retaining wall before dropping to the patio at the back of the house.
I want to dig out a larger patio area and use the soil to level out the gradient in the garden. This will mean a higher retaining wall I agree, but my concern is the boundary. It will have a lot more soil on the lawn as a result so what's the best way to retain that earth. Several people have mentioned using concrete slabs on their edge dug into the lawn to help retain the extra height. One said you will definitely need a concrete wall made with blocks. Not sure what is sufficient. Note the lawn is 13m wide. Any advice appreciated.

We've had a blustery night so excuse the mess but you can see the existing retention wall and that the slope is not drastic. It drops probably 18" over the entire length of the garden. On the bottom picture you see the lone tree. We will take the patio back to that point so aim to use earth to level out the slope coming down to that point. We'll remove the existing concrete paving that you can just about see behind the tree and create a border to plant in so want to retain the earth up until the neighbours' wooden fence that you see.
On the opposite side you notice we have it walled half way up then fenced (with gravel boards). I want something that will be independent of any existing boundary when it comes to earth retention. We may decide to wall it all the way to the back one day.
