Questions about the development plan

If the development plan states that the upper reference point determines the maximum wall height and a value of, for example, 314.34 is given, what does this specifically mean for the wall height? According to the development plan, 2 full stories are allowed. We would like to build with a saddle roof and a 20/25 degree roof pitch, and a knee wall as high as possible... How high may it then be at this value? See picture...

If the development plan states that the upper reference point determines the maximum wall height and a value of, for example, 314.34 is given, what does that mean concretely for the wall height?

It means the value from which the measurement must be made. Usually street level height; the city should have given you another plan in which the NN (Normalnull) values are entered. Otherwise, ask a surveyor.

Can you quote the exact text of the development plan? I can't see any image. Did something go wrong during the upload?

OK, I’ve now understood how to open the image. However, I don’t understand the stipulations of the B-Plan. What is the purpose of the stipulation regarding the lower reference point? Which wall height is meant, eaves side or gable side? For us, stipulating a ground floor level, eaves, ridge, and/or building height is common.

But I’ll just speculate: According to the sketch on the development plan, I think that in your case the wall height means the building height, since the second full floor with pitched roof surfaces is shown here. I interpret the lower reference point as street level, which must not be undercut by the ground floor level. The house with OBP 314.34 would have a 2.18m high gable triangle with 12m building depth, so with a story height of 2.80m the gable would be (314.34 - 308.34) - 2.18 - 2.80 = 1.02m.

But a call to the building permit authority would certainly be more informative.

I do not see an image and assume that the altitude refers to meters above sea level.

If a photo is posted, then not directly, but as a link, I suppose. And this image was deleted again in the home gallery?

Please only post direct attachments here if you expect responses.
