Problem due to zoning plan: Only 1 full floor allowed

Hello,

I have a problem with our house construction planning and would like to hear your opinion. I know it is difficult to give me solid advice here, but I still wanted to see if there are any experiences regarding this.

Since only 1 full floor is allowed in our development plan, we have planned a house with a recessed upper floor. Furthermore, we are building with a basement. Now the problem is that the sewer is not that deep, and we would either have to work with a lifting station or build the house higher out of the ground to avoid a lifting station.

I have to say that neither my wife nor I want a lifting station because the basement is also to be converted into an apartment for our daughter, and by "raising the house" we would also save money on excavation.

So far, so good, the problem is that if we were to build the house high enough out of the ground, the basement would count as a full floor because the average protrudes more than 1.50m above the natural terrain. The fact that we want to fill the terrain anyway so that the house does not protrude too far does not matter, because only the natural terrain counts, not the filled terrain.

Now we are wondering what would happen if we build the house high enough as planned, fill in, and thus have 2 full floors according to DIN regulations instead of the 1 allowed. I could imagine that a fine would be imposed, but I couldn't say if it would be extremely high? Aside from the fact that we do not believe that anyone will re-measure...

Maybe someone here is knowledgeable about this and has had such a problem?

Best regards

Hello,

first of all, I think you are approaching your development plan a bit naively...

Since only 1 full floor is allowed in our development plan, we planned a house with a recessed upper floor.

Stepped floor with 66% of the ground floor area or sloped ceilings in the attic?

Furthermore, we are building with a basement. Now the problem is that the sewer is not that deep and we would either have to work with a lifting system or build the house higher out of the ground to avoid a lifting system. I have to say that neither my wife nor I want a lifting system because the basement is also to be developed as an apartment for our daughter and by “raising the house” we would save money on excavation.

You need a lifting system in any case (with 2 shredders, since a toilet connection is required), as it is mandatory to drain "below the backwater level." You cannot circumvent this system by simply adding fill; the only exception I know of is if the property is on a slope and the public connection can be made on the lower side and if there is a sewer connection point there. Or: no bathroom is created in the finished basement.

Now we wonder what would happen if we built the house as planned high enough, filled it, and thus had 2 full floors according to DIN regulations instead of the 1 allowed. I could imagine that then a fine would be due, but I could not say whether it would be extremely high? Apart from the fact that we do not believe anyone will measure it...

You can believe that in church.

Why you cannot avoid a lifting system I already answered you above. AND I can assure you, someone will show up when you least expect it! In the best case you will be fined in the five-figure range, in the worst and most likely case, you have to rebuild; also in Hesse

Kind regards

Hi, Bauexperte is right
with certainly hefty fine and dismantling

Hi, Bauexperte is right with certainty hefty fine and dismantling
