In the garden, we need to build a retaining wall along 20 meters (65.6 feet). It will have a height of 1-1.2 meters (3.3-3.9 feet) and must hold back the soil on the property. It will only be supporting the garden. No road or building needs to be supported.
1) Which type of wall is more suitable? What are the advantages and disadvantages of a retaining wall with L-shaped blocks versus formwork blocks that are filled with concrete?
2) How should the foundation be prepared? Should it be gravel or a strip concrete foundation (how deep)?
3) What is the approximate cost per linear meter? Does anyone have relatively recent experience?

Setting your blocks initially on the property boundary seems like a hopeless attempt to me. That can only be done once the neighbor has installed their retaining structure—ideally, you both do this together with a continuous 3-cell wall.

This might make it easier to visualize.

Everything else will be a disaster.P.S. You won’t be able to prevent the visual disaster at the neighbor’s either...

P.S. You also can't prevent the visual disaster at the neighbor's...How far away from the boundary would I need to stay to prevent any soil slipping? We plan to hire a structural engineer to address this question. To what extent is a structural engineer liable if slipping does occur? And how responsible is the neighbor?
