How was the slope actually constructed? Slope insulation, screed? Is there only the one drain, i.e. the slope would have to go completely from left to right, or are there other drainage points?
I don't know anything about the construction. There is only the one drain plus the emergency drain next to it.
If greenery is added later then it’s really not a problem at all.

And in one picture it looks like the membranes are not glued flat and there are already air bubbles at the parapet?
Without greenery. Oh, I hadn’t even noticed the air bubbles :\
How high is the water? Hold a meter stick in and take a photo.
To me it also looks as if it’s sloping uphill to the drain and that is definitely a defect. And what slope is planned for the roof?
I don’t know if or how the slope is planned. I don’t see anything about it in the section. To put in a meter stick I’d have to crawl up there…uh oh… I’m somehow hesitant about that.
Just a theory, of course, but drains usually have to give way to the owner’s wishes regarding glazing and downpipes that are not routed over the glazing ;-).
We can just guess how the bay window looks from below/outside … I guess lots of glass, the cover membrane on top also suggests that.
At the front under the flat roofs there are windows, on the side where the drain is there are none.
For a start I would simply put a thick absorbent cord into the water (one end weighted with a stone). The other end goes into the drain hole. The cord draws the water to the outlet and lets it drip in… that’s the theory… zwbz.
Sounds good :) Could you possibly sprinkle a bit of sand or something on it in an emergency so that the water is absorbed and doesn’t keep trying to find a way down into the house?
Thank you all very much
