Must the balcony above the bay window be the frame?

Dear friends,

I am uploading the picture now. We are building a Reineck house and have a balcony above the bay window and cannot understand why it has such a wide frame. To go out onto the balcony, we have to take a big step every time. When I asked the construction manager (who can justify all the architect’s planning errors with regulations and DIN), this was the answer:

This upstand at the balcony door on the upper floor is correctly executed. As shown in the construction plan, a parapet of 25 cm was specified here. This is necessary in order to properly seal the balcony outdoors according to DIN 18531 (flat roof guidelines).

Does it really have to be like this?

I am excited for your answers.

It is like a windowsill, I have really never seen such a quatach before.

The insulation structure in the outdoor area is higher than your screed in the indoor area. This results in the step. It is simply the cheapest implementation of this detail.

If you do not want this, the screed would have to be higher, which reduces room height and affects the staircase construction. This request should be made early enough, and there will also be additional costs.

Regardless of the additional costs (we would cover them), what options do we have?

From my point of view at this point in time, there are no great possibilities left. What kind of flooring will be installed inside and outside?

What have you actually discussed about this detail with your architect? I already pointed this out to you last August, that such a construction could arise here, because the parapet height was already shown as 25cm in the plan.

Exactly, I remember very clearly and I didn’t understand you back then. I then asked the architect. She said something like many others were wrong. I assumed it would just be one height but not a board in front like that. Is there really nothing more that can be done?
