Garage on a slope / basement, L-shaped stones, erosion?

Hello Tabaluga,

presumably your garage construction has been realized by now. However, I can only advise caution. I am currently having problems with a neighbor (co-owner) who lives above me on the hillside. Their garage (about 4.50 m high, approximately 10 m long plus roof terrace) was simply placed on the slope on an 80 cm thick (frost-proof) slab at the property boundary, without any further support in the ground. Now, after 11 years, this garage is pressing so much on my property and house that I had to complain to the building authorities. Also, the builders of this house (3 1/2 stories) did not implement any hillside stabilization during construction. Here too, the slope is pressing towards my house. The property was apparently built up at the time and supported with more than 3 m high L-shaped concrete blocks towards my property. Independent of the oppressive appearance, these are already tilting 10 cm in my direction. I only acquired this house last year. My seller had planted the backside of the house so densely (probably for good reason, I suspect) that - except for the L-shaped blocks - nothing was visible. After the landscapers cleared the area following my move-in, the whole disaster became apparent. There is no talking to the neighbors.

I have the same luck, but I wanted a carport for the motorhome. I dug frost protection trenches 16m long and 5m wide and built the walls up with hollow blocks. On top of that stands a 60sqm, 3.30m high carport. (Which I bought on the internet in East Frisia) and on top of that I installed a 10kw photovoltaic system. The wall with the fill cost me roughly 5000,- The carport complete with roof and side walls 2800,- On vacation, I will continue with plastering and paving once the ground has finally settled, as I do not have a concrete slab.

Why don't you plan the garage at "basement level"? If there is enough distance to the street, you can easily get into the garage with a slope. We plan to do something similar. Dig about 1 meter deeper than the neighbor and shore up the side with L-shaped stones.
