Hello everyone,
definitely our most challenging topic in building the house is the design of the slope facing south. (the attached sketch is at a scale of 1:100, the elevation points are marked in red, the total slope length is about 20m (65 feet) including the inlet and outlet).
After numerous site visits, research, and discussions, the following options for materials are under consideration:
1.) Slope facing stones: inexpensive, feasible for DIY, but not at all to our taste visually.
2.) L-shaped concrete blocks: reasonably priced thanks to contacts at a nearby concrete plant; digging, crane placement, and foundation preparation would be partly doable as DIY; the appearance is so-so.
3.) Gabions: at least 1m (3.3 feet) thick and therefore a cost breaker (>10,000€; quote pending); visually very stylish and exactly what we want.
4.) L-shaped blocks with gabions as a cladding: L-blocks for slope reinforcement with a narrow gabion (30cm (12 inches)) as a facing; hmm, not seen this before or have experience with it.
The next question is also where to start intercepting the slope? At the location shown in the drawing, or extend the slope to the southern property boundary in order to potentially secure the fence there with L-blocks. The appearance would then theoretically not matter, as we wouldn’t be looking at the blocks, only the neighbor would (the house is still at the shell stage). The disadvantage would be needing a huge amount of backfill soil. Up to 2m (6.6 feet) height at the property boundary would also be permit-free in our area.
Looking forward to your opinions

Understood,
Offer for 1.) approx. 60€/m² (approx. $6/ft²)
Offer for 2.) €39,000 ($42,000)!!!So, what are you going to do now?
Best regards, Yvonne

We are currently checking the costs for 2.), meaning L-shaped retaining blocks, and we are thinking of placing them directly on the property line and using them as a boundary wall. Possibly about 1.5m (5 feet) high, with a fence on top for fall protection. Then there would be a step of about 0.5m (20 inches) down to approximately ground level, which we would fully handle ourselves—maybe with gabions halfway between the house and the southern boundary.
The meeting at the building authority was also very informative. Structural engineering approval and a building permit/planning permission are mandatory because more than 30m² (320 ft²) has to be filled in; otherwise, we would have gotten away without it...
