Children's room on the upper floor open up to the roof

: If you google "Danhaus rundgang engelsby."

There is then a ladder from the children's room up to a kind of "mezzanine." Our little one really liked that. But my wallet didn't.

I don't think the OP curly means something like that, since the gable is not open.
At Danhaus, there is a floor hatch leading to a converted attic.
In Edition 220, the gable is open into the roof. Many shed-roof houses have that as well.
In the row house where I lived, there was that too: the center of the room was 3.40 meters high, and many built a loft bed there for their child.

: There is then a ladder from the children's room to a kind of "gallery". Our little one really liked that. But not my wallet.

I just took a look at it... not bad either and my daughter would like it too, it's like her own little cave. Have you asked what it would cost?

Best regards

On the topic of roof windows, you really have to weigh the pros and cons. On the one hand, high-quality roof windows are quite expensive and, above all, cleaning them annoyed me a lot. Even if you can rotate and lock them in all directions, water still drips down repeatedly. It’s annoying when you have your bed under the window, even if it’s a waterbed. Then there's the aforementioned pattering when it rains or even hails at night. More than once, I lay down on the couch because I couldn’t sleep under the window even though I had installed the best soundproof windows possible. Another downside is that if you need the windows for ventilation and it snows heavily overnight, you end up with all the snow inside the room/bed. It never got too warm for me in summer either, because the apartment/the roof was insulated well enough. Of course, the windows also have advantages. Since they are angled upwards, you get more light with the same window area, and especially in winter it can be very pleasant to lie under the window when the sun is shining despite the cold temperatures outside. My window was 160 cm high and over 100 cm wide; lying in bed underneath, you can also romantically watch the stars. All in all, however, it was/is too much effort for me (both financially and especially in terms of maintenance), so I no longer wanted roof windows.

Have you ever asked what that would cost?

I seem to remember being told something about €6,500 during the conversation (but that was a while ago). And back then it didn’t sound like a final price.

The topic is also interesting to me, does anyone here perhaps have more pictures? Unfortunately, not much comes up in the google search.

We will also have such rooms on the upper floor, have a look at meisterstueck.de under Medien 360° at the show house in Cologne. We are planning with a knee wall of 2.20m and will have the "open roof" everywhere. For us, that was no extra charge. We have only one skylight, in the dressing room, because only there was no space on the wall for windows...

What we were not aware of beforehand, however, are the practical problems afterwards with the furnishing: We do not want ceiling spotlights, so it is not so easy to find lamps that can also be hung on a slant. For me, "wedging" under the lamp base is an unsightly crutch. Also, the light is not reflected as well because the ceiling is already far away. We only have a 20° roof pitch, but in the middle the room is already very high.

When you are inside the room, however, it is a really great feeling of space and gives a sense of "freedom"...
