Idea generation for a single-family house on a slope. Tips welcome

Hello everyone,

I am new here - but I read your posts with great enthusiasm.

Now to the topic:

My wife and I would like to build a single-family house on a hillside. There are some regulations regarding the development plan (36-42° gable roof, knee wall 0.25m, enclosure, etc.).
The plot - actually two plots - has about 1,100m² and slopes downhill.

Our idea is to enter the house from the street, then go down to the living area to get outside onto the terrace.
What we want to avoid is giving the impression of going into the basement.
In old age, the lower floor could also be converted to live completely downstairs and make the access around the house.

I have anything but two left hands and there are many construction entrepreneurs among friends and family, so we want to do a lot ourselves.

What is also important to us:
I need a large workshop. My wife would like an open staircase with an atrium. Two children’s rooms, and large open spaces. Small fireplace in the living room.

House building info:
Preferred heating - pellet
Hollow brick 48.5 without insulation?
Underfloor heating, solar

Attached are self-drawn plans according to our ideas. It would be great if you could share your opinions on them.

So on a slope without concrete walls? We have Dad's roof standing like yours, our living space is also in the basement, garden to the south. On the slope side we have only concrete walls below, I don't know if I would have them conventionally bricked. What is the box actually allowed to cost? That seems like quite a lot per cubic meter of enclosed space you see there... the price will make you dizzy. Why pellet, are there reasons for that?

Thank you for the answers.
That's right, the slope location should be made of WU, it was forgotten. How does the transition to the stone look?

Does the building appear too large?

I have good experience with pellets, and many friends in the area with whom simultaneous delivery is worthwhile. We have also calculated with pellets in terms of available space – if the heater becomes smaller, I still have storage space.
Alternatives to the heating?

So with us, insulation started from the basement with 16cm. The rest then 24cm with 16cm WDVS. The transition to the stone is each time only after a few meters around the corner. So where the walls then stand free. We have a gas cylinder, that was the compromise, I had initially flirted with an air-water heat pump. But since we unfortunately also had to build 3 floors or rather a pitched roof on top according to the development plan, we also have 1000m³ enclosed space, the heating load was 9kw... I thought we would come down further. But our garage is included in the ground floor thermal envelope, which did not make it easier. So I think this is a big building you are planning... but it would be nicer if you could upload the plans as jpg, with the pdfs the whole thing is very tedious to look at.

Can you please change the PDF files to JPG and fill out the questionnaire.



At first glance

Attic
Children's room does not work. 20 sqm sounds like a lot, but with the knee wall and despite the roof pitch, there is hardly any standing height. Draw in the 2 meter line.
Bathroom as well.
Hallway extremely large for nothing

Ground floor
Lots of hallway even if it is designated for reading and working. Why no separate office?
If reading corner, then also space for shelves
Sleeping, dressing, bathroom small in relation to the floor area

Basement generous
What's the point of a bunker where you get claustrophobic

Very large house, almost bulky, very few rooms and those are very small. Without quality loss it can be much smaller. Definitely check the 2 meter line in the attic. It should be similar to ours and with that, such rooms do not work

On the slope side, we have a white wall and the free walls are solid wood. Your UG is basically our EG. Garage downstairs, building services, entrance, bathroom, and a multipurpose room. The OG has one bedroom, 2 children's rooms, a bathroom, and a laundry room (where the laundry also accumulates). The DG is not developed but within the thermal envelope.
