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?

He has to place the wall bracket on your property, have you considered that?
He doesn’t have to; there are support brackets with the angle facing inward, called “visible side inside.” However, these are significantly more expensive.

Yes, yes, not only more expensive, the base at a height of 2 meters (6.6 feet) is about 2 meters (6.6 feet) wide...

No. At 3 meters (9.8 feet), the base is 165 centimeters (65 inches) long.

Honestly... a terraced garden... how can anyone seriously plan to completely level such a slope by cutting and filling, and then build a 3m (10 feet) high wall?
You can't be serious?

The topic of the drainage application was briefly mentioned without going into detail. A similar case has occurred in our development area where the lower homeowner, who has built into the slope, is experiencing significant water leakage and a wet, waterlogged garden. This poses an additional potential for conflict and should not be underestimated.

This project involves more challenges than it might seem at first glance. I didn’t ask without reason whether it would be an option to keep the natural terrain; I would at least consider that. Next comes fall protection—okay, a fence could also serve that purpose, but then it would become an issue for your neighbor.
