Hello everyone,
I have another question that’s been on my mind. We are currently having a semi-detached house built through a developer. On the top floor, there is currently a knee wall with a rough construction height of 50 cm (20 inches) as standard. The roof itself rests directly on the floor, so there is no knee wall, if I understand correctly. But somehow, it feels incomplete like this. The drywall contractor has now offered to move the knee wall forward to 1 m (3 feet). The cost is 280 euros net for just under 6 meters. He needs to know soon for some reason.
I thought this would come after the underfloor heating and screed installation. Or how does that usually work? What would be behind the wall then? The floor without screed? That would be quite dirty for storage space.
Wouldn’t it be more practical to leave the knee wall out completely and do it myself later? I imagine it all being a bit “cleaner” regarding the flooring and so on. But then the roof would meet the floor at an angle. That could be an issue in terms of appearance.
Maybe you have some tips for me. What makes sense, what is worthwhile?
Thanks a lot!

What do you mean by "42"? It’s the answer to “life, the universe, and everything.” A meme from "The Hitchhiker's Guide to the Galaxy." 42 is the universal answer to questions that are too vague.
When it comes to storage space behind the knee wall, keep in mind these are really crawl spaces. They’re fun as a child, but as an adult, you don’t want to store anything there that isn’t right by the door.

There is definitely no knee wall. The roof rests directly on the floor and has a slope of 33 degrees. Do you need any more information? You need to decide whether the confidentiality level of your building plans is worth not getting a useful answer, since a general response is unfortunately not possible.

Adding a small door to the knee wall definitely adds to the cost if there is going to be storage space behind it. [...] For items you rarely need, it’s a good storage solution. I don’t think so, Tim (also a quote, Albert Borland). Such a tiny knee wall doesn’t create a proper storage recess. At a height of 50 cm (20 inches), it only works if the entire knee wall is removable; I would rather reduce it to 20 cm (8 inches) and then seal it completely.

At a height of 50 cm (20 inches), this only works if the entire knee wall can be removed; I would rather reduce it to 20 cm (8 inches) and then close it off completely. If I understand correctly, it’s about increasing from 50 cm (20 inches) to 1 m (39 inches), and at 1 m (39 inches) you can actually use the space somewhat. Although even then, it will mostly be suitable for less important items or things stored right by the door.

C.beckmann198629 Dec 2020 23:21I just reviewed the plans again. If it helps, I can gladly share some details.
According to the plan, the knee wall (dwarf wall) is currently designed to be 50cm (20 inches) high. Behind it is only concrete, no screed. In front of it, there is screed with underfloor heating.
We could move it forward to 1m (39 inches), but then there probably wouldn’t be any screed behind it, which would cause a difference in level. Additionally, this would be the “unfinished state.”
I would prefer a knee wall with flooring and screed since it’s a living space.
The idea would be to keep the standard knee wall at 50cm (20 inches) and later build something on top of it ourselves—so a knee wall in front of the knee wall. Or reduce the standard to about 20cm (8 inches) and possibly build a knee wall later as well. However, this would likely incur additional costs for screed and so on. I haven’t received any feedback on that yet. With the second option, there would naturally be more “space” inside the knee wall.

Attention: Underfloor heating is not installed behind the knee wall, and this area is sealed off with panels and silicone since there is nothing there. According to the scope of work description, storage space is apparently not planned there; instead, it is sealed off by the drywall installer. Therefore, it is a cold crawl space, comparable to an unheated attic.
Anything you choose to do yourself or omit will affect your home's energy consumption and the related calculations.
