Hello,
Since our carport driveway would probably be too steep if we build the carport level with the house (or with the adjacent room used as a "basement replacement"), we want to position it lower, at street level in this location. The height difference to the "basement room" would be about 75cm (30 inches) at most. Could this be supported with (proven) L-shaped retaining walls over a length of around 5m (16 feet), and if so, what costs might be expected, including for the foundation of the walls?
We would not connect the carport directly but place it about 2m (6.5 feet) away, so the necessary stairs would not be within the actual carport area, while also creating a strip where, for example, trash bins or a bicycle could be stored. I hope my explanation is clear?

There are three types of permanent support structures:
1) Planting rings filled with soil and planted. Affordable, functional, and visually acceptable when covered with vegetation.
2) L-shaped concrete blocks. I find these unattractive; they always look like highway construction.
3) Frisian walls made of natural granite or basalt. Attractive but unfortunately expensive.

If you measured 75cm (30 inches) yourself, then with excavation, leveling, and laying the foundation, you'll end up with 1m (39 inches) L-shaped concrete blocks According to the surveyor’s plan, the height difference between the highest corner of the house and where the blocks would be used is approximately 65cm (26 inches). However, we will probably excavate a bit at the higher point, so the house will be set slightly lower, reducing the difference... meaning the 75cm (30 inches) should actually include the leveling and so on. But if it ends up being a bit more, that wouldn’t be a problem either.

3) A traditional berm made of natural granite or basalt. Attractive but unfortunately expensive.The latter option obviously looks nice, but in our case it probably isn’t feasible (even if structurally possible, it would certainly be too costly).Similar topics
