Hello everyone,
After a long search, we have finally found a plot of land that we want (and can afford). Now the question is how to build.
To explain briefly, it is a slight slope parallel to the street. In front of the plot, there are two parking spaces, so the driveway can only be on the upper left side.
A soil report states that the soil is clayey. Building is allowed at 200 meters (656 feet) above sea level ± 0.50 meters (1.6 feet). The total height for shed roofs must not exceed 7.50 meters (25 feet). The shed roof must have a pitch between 10° and 15°, the orientation does not matter (preferably facing south due to a planned photovoltaic system). We would like to build two full stories.
The construction will be solid masonry, but we are still undecided between aerated concrete, clay blocks, or Neopor concrete.
Now the question is whether it makes sense to plan a basement, which would only be used as storage and for the building’s technical equipment. Possibly, depending on the size, also for a hobby room.
On the topic of basements, you find very different cost estimates ranging from €15,000 to €70,000. Since the basement will be finished by ourselves, I am mainly interested in the cost of the basement shell itself, not the complete finish.
Is a basement even possible with the maximum building height and two full stories?
What are the additional costs compared to building without a basement? Because of the slight slope, quite a bit of excavation would be required to create the foundation for the slab.
To give you a rough idea of our plans, I have attached two images.
The red numbers indicate the elevation in meters above sea level at the corners.
What do you think about the basement? We find it hard to design a floor plan where there is enough space on the ground floor for both the technical and storage rooms. But we also don’t want to “bury” unnecessary money.
PS: I’m happy to receive suggestions for the floor plan as well, but the main focus should be on the basement question.

Our building site varies from meter to meter. Some had to use blasting, others chiseled for days, and some only encountered a few meters of rock.
Our soil report looked like this: not drillable beyond 56cm (22 inches). That’s fun.
So please have your own report created and make the drillings where the house is actually going to be built, not in random corners of the plot.

Exactly – I certainly did not mean to suggest cutting costs on your own assessment. The neighbor’s report is, of course, not suitable. In a survey for an entire development area, however, the sampling points should be spread widely enough to reveal signs of inhomogeneity. The more locations examined, the less likely it is that any anomalies were simply missed by chance.

We have now had the opportunity to talk with the surrounding neighbors. Only one built without a basement, and except for one, none had a soil survey conducted. Apart from larger stones or rocks, nothing significant has been found. I believe it is purely a matter of cost.
Does anyone have experience with Kern-Haus?

Hello,
A quick note about the slope: we had a height difference of 2.4 m (7.9 ft) over 31 meters (102 ft) and thought it wasn’t much...
It’s about 750 cubic meters (980 cubic yards), so 1.5 tons (1.65 tons). Calculate this in advance, otherwise you can easily face an extra cost of 10,000 to 15,000 euros, which will literally be wasted and was not planned for.
We estimated 430 cubic meters (560 cubic yards) and 860 tons (950 tons), but in the end, it was the value mentioned above...
Please don’t underestimate this!
Best regards
