Building plot evaluation and house orientation

That is all complicated. I never understand why it isn’t just fixed.

State building code?

How wide does such an embankment have to be?

In our case, the development plan stated no higher than 50 cm (I think that was also the case), but no L-stones, instead slopes up to 30 degrees were allowed. This meant, conversely in our case, that at 30 cm height you have a slope falling 1 meter. This simply ensures that no soil falls onto the neighbor’s property. Many have just solved this by planting the hedge on somewhat sloped terrain.

State building regulations?

In our development plan it said no higher than 50cm (I think that was the case), but no L-walls, instead slopes up to 30 degrees were allowed. That meant, conversely in our case, that with a height of 30 cm you have a slope dropping one meter. This simply ensures that no soil falls onto the neighbor's property. Many simply got around this by planting the hedge on slightly sloping terrain.

mh okay I’ll read up on the state building regulations again. Unfortunately, our development plan doesn’t provide anything. Otherwise, the building authority will probably give information, right? Are these special bushes?

Neighbor B is actually responsible for the enclosure of our property. But in this case, we would have to take care of it.

I have recalculated it.

Assuming we fill up the entire plot, which will probably be really expensive because we cannot fill the whole plot with the excavated soil.

Assuming neighbor B remains as he currently is. Then the difference after our filling would be at most 80cm over a garden length of 7m from the house, so you could make a slight slope of 11°. Are 11° a lot? Unfortunately, I have no idea how to estimate that.

Thank you!

Do you think it is a problem that the neighbor has piled up so much

If it were one, it would be a problem for your neighbor. Whoever changes the terrain must ensure that no one comes to harm.

Do you think the orientation of the house makes sense?

Yes.

or narrower

Yep.

Only that you are not allowed to be higher than 0.5m above the reference point.

The reference point must be defined in the development plan, otherwise it would be an indefinite provision that would lead to the invalidity of the development plan. This mistake no longer occurs nowadays.

I always don’t understand why this is not simply defined.

Then you have to show us the development plan. Maybe we can explain it to you then.

Unfortunately our development plan doesn't provide anything.

I don't think so.

80cm over a garden length of 7m

is 11% or 6°. Not insignificant. Barrier-free ramps may have a maximum of 6%. I would build a small retaining wall directly at the terrace.

Hello,

thank you very much for the answers and the drawing. I have a few more questions regarding this. They are listed below:

Attached, I have once again included a few files. I have marked our plot on the site plan with the utilities. On the site plan, the values written in a blurry manner are the current ones, and the sharply written values are the planned values.

We are orienting ourselves on the gray street, as the access is also drawn in there. Our developer has assumed level 0 here. Is it correct that we took level 0 here? The plot is a corner lot and has a slight slope. Or do we have to take some kind of average value?

How should we ideally set the height of the house with the bottom edge of the floor slab? We would leave the carport/courtyard at about 0 or raise it slightly towards the back so that water does not stand in the yard. Could there be problems from the building authority if we fill up that high? We only want to fill up as much as necessary under the house.

Our neighbor on the red street (in the photo at the bottom right) clearly has a lower level, already from his street. Since he accesses from the red street, he will also remain at that level. How can we best equalize the levels then? How wide does a slope towards him have to be so that we do not get any problems? We do not necessarily want to put in L-supports. Especially at the back end in the corner of the plot, the level difference is quite high.

We will also have to flatten the terrain to the red street on our plot. Here, we could either create a continuous slope or a step down from the terrace to the garden, or are there other possibilities?

The development plan only mentions something about the eaves height/ridge height and floor slab height (see attached). It says that the middle of the street should be taken as the height. Does that mean the middle of the gray street?

I also have a question about the utility plan: What does this black/white circle in the middle of the plot mean?

Site coverage ratio: The development plan only gives 0.3. Can we still use 0.45 for site coverage ratio 2? (Lower Saxony).

Many thanks!!

Or do we somehow have to take an average?

Yes, "middle of the street property boundary." Gray: (65.00 + 64.77) / 2 = 64.89; Red: (64.48 + 64.60) / 2 = 64.54

How should we ideally set the height of the house with the bottom edge of the floor slab?

The bottom edge of the floor slab depends on the construction. The finished floor must in any case not be above 64.89 + 0.50 = 65.39 if it is to be connected from the gray street, or 64.54 + 0.50 = 65.04 if it is connected from the red one.

Could there be problems from the building authority if we build up that high?

For that, one would need to know the complete development plan including textual specifications.

That means the middle of the gray street?

"Middle of the street property boundary"; my interpretation: middle of the property boundary adjoining the street selected for connection.

What does this black/white circle in the middle of the property mean?

These are the gradient points of the drainage planning. Since you were very sparing with the choice of the excerpt, I cannot explain it in more detail based on the drawing.

The development plan only states 0.3. Can we still calculate with these 0.45 for the floor area ratio 2?

Yes. However, if you continue to withhold the development plan from us, these are just assumptions.
