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.

Thank you very much. Do you happen to have elevation surveys of your property?
The site plan could also be helpful.
We understand that the costs are difficult to estimate, but we want to try to plan a bit more to be on the safe side.
Unfortunately, we are struggling a lot with the building’s floor plan. The upper floor is almost secondary. Current floor plan
The blue area is intended to be a sauna.

Hello everyone,
It took us a while, but now the plans are finalized and the building permit / planning permission application is about to be submitted.
We have some new questions:
We want to install underfloor heating and a controlled mechanical ventilation system with heat recovery.
In the basement, there will only be radiators.
On the roof, there will be a 10 kWp photovoltaic system.
For heating, we plan to use an air-to-air heat pump.
A heating load estimate results in about 8500 W.
The estimated hot water consumption is around 1300 kWh/year.
Now the questions are:
How did you implement your heating system?
Which model did you choose?
Would you go for a combined unit or prefer separate systems?
Are these estimated values realistic?
If you want, I can also share the final plans.
Regards

Really air air? The little man sucks and blows where Mom can usually only vacuum.... Or air water?
How do you produce hot water for the bathroom and for the heat pump?Good observation. Of course, it’s air/water. Underfloor heating with air would really be uneconomical.
