Floor plan single-family house on a slope

or you fill the garage with the excavation from the house.

There are also natural slopes outside of the [Truppenübungsplatz]

We currently think that not that much will be produced (the slope is quite steep) and that the best use for it is to level the garden ... One architect sees it similarly. But we are not yet in the detailed planning, so this assumption might still change.

Yes, the topography is quite interesting, that's true. :D

Could you please explain the tip for a decoupled garage? Because of the elevation profile of the terrain? Because otherwise it becomes expensive to align the garage and the house? Or are there other reasons? Thanks!

There are also natural slopes outside the military training area

Yes, but then it must have been a very playful nature here - and one where the cat was out of the house ;-)

I also think that a lot can be done by redistributing. But I have to sprinkle two drops of bitterness into your dreams: first, every digging bucket really costs - including those with "own soil donations" - and second, you don’t build the volume back 1:1, but have to at least (I believe, roughly about a quarter) replenish "compaction loss".

About @haydee’s motives I could only speculate, mine would be the following: 1. the more lively the terrain undulates, the more complicated it is to determine a fair ;-) common denominator level. With a decoupled trailer parking may be easier. 2. I see the most suitable place for the garage at the (north) border. However, the state building code then limits the “average wall height” to the neighbor, which, as far as I know, typically refers to the original terrain. In my view, the development plan makes the exception from the usual (the height references to the terrain before modeling) only for the house. But if you then rigidly weld the house to a garage - which itself has a height limitation based on the original terrain - then you lose the freedom and flexibility that the development plan has wisely actually built in here. In addition, with the filling, the cards "per basement under the garage" get some bonus aces smuggled in. I would find that a (too) high price for a connecting door, which in Grandpa Willy’s spirit belongs anyway to the category "overly diligent like a crow". I have — damn, still haven’t measured — over 500 m between front door and garage door, naturally not covered ;-)

I can only agree with 11ant

And I am and will remain in favor of exchanging the floors and better use of the attic. There are stairlifts for stiff bones

Gallery above and airspace look like a spasmodic use of an unwanted area.

What a pity. :( This is one of the most desired areas.

Always draw all furniture to scale in every floor plan. Go through everyday life.

I will do that in the future!

I also see the garage opposite the house about half a meter further away from the street lying correspondingly lower in the terrain (20, 30 cm ?) and having a slight slope in the driveway (which should be unproblematic with a bird gutter).

Wouldn’t a fall be extremely unfortunate regarding water drainage, possibly also because of snow/ice in winter?
The architect even spoke of trying to raise the house a bit because of the water. I think he included the garage in that.

Thank you very much for your detailed explanation regarding the decoupling, that helps a lot! :)

2. I see the most convenient place for the garage on the (north) boundary. But then the state building code limits the "average wall height" to the neighbor, and as far as I know, that usually refers to the original terrain.

Hm, so far I have been given the following regulations for a garage (and yes, we also see the garage in the north): The outer surface to the neighbor may not exceed 25 sqm (if it is a boundary garage), it must be set back 5 m from the street, and the height from the street side (whatever level is meant by that) may not exceed 3 m.
So far, we do not yet see a problem with possibly moving it 2.50 m to the right if the outer surface would become too large. Then you could make a parking space or something for the garbage bins on the left towards the boundary?

Duly noted. :)

Would a slope not be extremely unfortunate regarding water drainage, possibly also because of snow/ice in winter? The architect even talked about trying to raise the house a bit higher because of the water. I think he included the garage in that.

I was talking about the Bircorinne (in front of the garage) because of the water. For the house, I would also (but not necessarily) prefer a raised elevation – however: the more, the more likely I see the "Pro Living-Basement" faction "winning" :)

So far, we don’t yet see a problem with possibly moving it 2.50 m to the right if the outdoor area would become too large.

Two and a half meters means BaWü? I can hardly judge that, as I lack measurements in the representations of the property.
