Good evening everyone,

I have been following this forum for a while now and am really impressed by how many tips and useful information can be found here.

Attached is the plot of land I intend to buy. It is 649m2 (approx. 25x25m).
My main question now is at what level we should most easily place the house/garage/terrace or even the entire plot?
Honestly, I am also a bit worried about the costs.
Next Monday, I have an on-site meeting with an earthworks contractor but would like to get your input beforehand so I don’t go into the appointment completely unprepared.

The neighbor on the left (1756/20) is at about elevation 540.5, the neighbor above (1756/22) estimated at 543.
The neighbor above has already built a retaining wall on my side of the property.

My idea is to bring the house + garage + terrace up to street level (about 542) and let the rest of the land slope gently down.
Is something like that even possible?
That would mean building some kind of wall towards the street (Buchenweg) / left neighbor, which would naturally cost quite a bit.
As you can tell, I am not very experienced and appreciate any suggestions.

Unfortunately, the numbers aren’t very clear on the plan, but I hope you can make something of it and I look forward to an engaging discussion.

Sorry for the amateur drawing, quickly done on my phone; north is exactly at the corner where the garage is located.
The house is about 10x10m, plus a double garage about 6.5x8m.

Thanks in advance!

Regards

- I don’t quite understand your “left” and “above” references, but how much fill is allowed is often specified in the zoning plan (development plan / local plan).
- I can’t imagine that constructing a fill towards the street is permitted, but that’s just my opinion.
- The general rule is: make as few changes as possible and model the house to fit the site, possibly by using a basement level.
- Retaining walls might bother some people, but you could hide them yourself with a planted slope.

Are you in a depression, with only the neighbor on the left side of the plan at your elevation? How is the street above on the plan? What about the street on the right side of the plan?
If anything, I would suggest terracing the garden. A gently sloping garden doesn’t feel right and isn’t really useful.
It’s best if you upload some photos.
And a tip for you: use modeling clay to recreate the terrain. Then use another color of blocks to represent the house, basement, garage, and fill. This way you can see the effects and possibilities, as well as the effort involved. This won’t be a standard house, and it will definitely be expensive.

No, basically the planned street slopes from left to right.
The left side of the plan is about 1.5m (5 feet) higher than the right side.
Since we want the entrance to the house on the right side of the plan, it is essential to raise the house and terrace to street level.

Adding fill material is not a problem there; on the street, there are several houses built significantly above street level.

The left side is about 1.5 meters (5 feet) higher than the right side.
Since we want the entrance to the house on the right side, it would be necessary to bring both the house and the terrace up to street level.

You still haven't clarified how your plot relates to the street.
Let me break it down:

Street!

Street? Street! Or the plot? Or both? I assume you mean the street.

So? Based on your first post, your plot is lower—meaning in a hollow. But now you seem to deny that... hmm

The heights can be seen in the screenshot; zooming in a bit might help to see them more clearly.

... and that’s why I asked if you are located in a depression.
You should be able to provide a precise answer rather than referring to the drawing when asked. In the end, your figure has been corrected, whatever that is supposed to mean.
I’m signing off now as it’s very late... good night.
