Glass roof over sleeping rooms, sounds of rain

Is this only about the 2m strip? I would put the beds under it and a wardrobe

then the room is out as a living space because it's overall too low.

to create a nice home for myself there.

So it’s not about others, but about you or your family?! You don’t know how you react? As a child, I could sleep very well under a large roof window at my parents’ place. When it rained, it always reminded me of the time when I was camping with my parents and thus calmed me down. And yes, there are many campers, whether in motorhomes or caravans – all with roof windows – I have never heard anyone complain that they can’t sleep. I’ll take a chance here: those who fear disturbing rain noises also think that they will _always_ get wet when going from the car to the front door and therefore _absolutely_ need a door from the garage into the house. It’s a matter of upbringing, to be able to adapt and not complain about every little thing :cool: For warmth, there is thermal protection foil for roof windows to retrofit. Then there is certainly special glass that does not let heat through 100%. Such things also exist for commercial use. It is also allowed to be dark tinted on the roof, which is normal for daylight in the North.

then the room is excluded as a living room because the overall height is too low.

In every house with a pitched roof, there are also plenty of square meters with ceilings under 2 m. Those are also living areas.

Polycarbonate is primarily found in industrial construction. They are practical because they are inexpensive and lightweight. But not much more. They also do yellow quite quickly. Even though high impact resistance is advertised here, they are still very susceptible to hail.

For roof surfaces, colored elements can be used.

In every house with a pitched roof, there are plenty of square meters with ceilings under 2 m. These are also living areas.

But not constantly. Here the shed roof is very flat... the heights are regulated in the state building code. I also guess it’s for rental, because otherwise the value of the sqm living area would not be the focus.

I also guess it's for renting, because otherwise the value per square meter of living space wouldn't be the focus.

But the OP says he wants to have it for himself.

I am currently planning an attic extension of a multi-family house to create a nice home for myself there.

I know, I quoted it myself in #19! However, if you stay in this forum for a while, you know that writing and intentions are not always the same. Here, however, it is not so important, since the argument from the OP is understandable.
