Floor plan of a single-family house 155m², without basement, 3 children's rooms, 1 office

Schema building body (building proposal with ridge direction suggestion)"

But that is a picture from a sales offer. Is there also an official site plan that one can take a look at?

for a comparable floor plan with a total of 10 sqm less living space and without a wooden facade, we received an offer from a prefab house company for 505k turnkey.

With or without the garage? With or without a base slab?

Technology gladly in the garage to have any noises “outside”

If that is allowed in QNG? The technology must be inside the thermal envelope, so in an outbuilding it is naturally an effort with insulation and supply lines. For us, the enclosure of supply lines with a base slab would not be permitted.

We will not build 100% turnkey, even if I wrote that above. But the owner’s work will be relatively small, so I did not list it separately. We will probably only lay the floors ourselves.

You can hardly call that own work anymore because 95% of construction companies (including or especially the well-known ones) do not include floor coverings in their turnkey offers. The same applies to the remaining painting work. Nowadays you already have to paint the staircase yourself and the treatment of the underside of the roof is also no longer included.
Every company has its own description of services where you cannot tell at a glance what is included in the “turnkey” offer and what is not.
The 3000€/sqm refers to a plastered standard house with plastic windows.

And now to the design:
I would also place the house entirely in the north to have the garden in the south and west. For that, I would follow the slope of the terrain. That means: house with ridge direction parallel to the street, as the sales brochure suggests. And then open the rooms towards the garden with windows. With a rectangular floor plan, you could also generate three reasonable children’s rooms.
What I find well thought out is the spacious hall with the huge closet and the terrace door in the kitchen.
Otherwise, much can be improved: the door swings and the locations for the closets, the children’s rooms—three of them—I have seen better solutions, nobody would get me into the utility room as it is so uninspired... my 4 sqm smaller utility room is more appealing, and then the living room with its rather sober possible furnishing.

Is the upper building limit also the property boundary? Then you still have to keep a distance (3m?).

As already suggested, the house should be moved closer to the street.

That is the maximum you are allowed to build.

I hope the roof pitches are not misinterpreted like that as well.



Basement, ground floor, and attic with knee wall or a recessed top floor with flat roof.

I would place the house and the garage as far forward as possible.

I assume that the zoning plan creator is assuming a gable-end construction.

For one car, the garage will work. If a second car ever comes along, then it is too narrow to quickly slip a trash bin or a bike between the cars. If this is desired, I would recommend an interior dimension of about 6.5m.

[Technikbereich in der Garage] you have to insulate like your house's thermal envelope.

If the original ground falls more than 1.50 m at the building, measured along the fall line of the slope, a building in hillside construction with a basement + ground floor must be erected."

Unfortunately, I just read this. Then you can also use the image you used if the house is only 8 m wide.

The basis is that the plot is surveyed with detailed heights (especially in the area of the house).

It must be clarified in advance what is meant by excavation and filling. Because the image at the bottom right will then not work.

Perhaps your interpretations of the development plan are also somewhat inaccurate.

Just because this caught my eye here.

So we are currently building a "similar" house. ~170QM, timber frame construction, wood fiber insulation, wooden windows, oak folding staircase, plaster facade, interior painter's fleece and oak parquet, etc. etc. local rather small provider, KfW40+, gable roof, but for the house with only 30sqm garage (prefabricated garage) including photovoltaic system with storage at 571k€ all in including base plate and earthworks. Not included are land, purchase incidental costs, outdoor facilities, architect, others.

Is there also an official site plan that one can take a look at?

Am I correct in assuming that you don't really want to disclose or comment?
