Retaining block wall

[LiamWheldon]

Hi,

I'm about to start building my first wall (already laid the foundation) but I’m not sure if I need a single wall or double. The actual wall is going to be 1m high and retaining 60cm of soil as there is 40cm of soil the other side anyway.

I'm using high density concrete blocks.

Any advice? The main question being will i need single or double. It’s going to be a patio area at the top and thinking about using those square decorative blocks on top as a safety barrier

Regards
Liam

Build it 225mm thick or double skin.
