ᐅ Knee Wall in a Danwood House in Schleswig-Holstein – What Are the Maximum Possible Dimensions?

Hello everyone,

I have a fairly simple question.
I want to build the 169A house from Danwood in Schleswig-Holstein. I would like to have the knee wall as high as possible (the catalog specifies it as 2 m (6 ft 7 in), but that apparently doesn’t work).
There are only two restrictions in the building area:
1. It must be a single-story building.
2. The ridge height must not exceed 9.5 m (31 ft 2 in).

I have already given it some thought and documented it in an Excel file. I would appreciate it if someone could tell me whether everything is correct or just generally advise how high the knee wall can be built given the dimensions of the house and the regulations in Schleswig-Holstein.

Thanks a lot!

However, I don’t understand 11ant’s initial calculation.

Are you referring to the one where I estimated how high the knee wall could theoretically be if only the ridge height limited it? – That was just to show that, in your case, the full-story box is actually the more significant restriction.

Could it be that your actual question should have been: "I want to place a Danwood Point 169A on my plot, and I assume it has a 2 m (6 ft 7 in) knee wall. Will it fit on my property with that?"

If so, the answer would be:
1. In terms of ridge height: yes;
2. Regarding avoidance of an additional full story: no, with that knee wall height.

3. However, you can still build this model. I see it working with a 1.80 m (5 ft 11 in) knee wall. For that, I would suggest the following changes: a) switch to roof windows in the air space; b) add a dormer to the walk-in closet; c) omit the second walk-in closet in the bedroom for spatial and ceiling height reasons so that the bedroom and bathroom can be shifted together and each can have knee wall storage. That would be that, as my late grandmother used to say.

With Danwood, it would not be a problem to lower the knee wall. This would even make the house overall cheaper, but the sales representatives cannot say how high the knee wall can be. That would have to be calculated by an architect. However, I came here hoping that someone could calculate it for me before I spend money and have it calculated by an architect.

Then the answer would be:
1. Regarding the ridge height: yes;
2. Due to the avoidance of a full story: no, not with that knee wall height.

3. However, you can still build this model. I see it working with a 1.80 m (5 ft 11 in) knee wall. For that, I would suggest the following changes: a) switch from an open loft space to roof windows; b) add a dormer to the walk-in closet; c) for surface area and standing height reasons, remove the second walk-in closet in the bedroom so that bedroom and bathroom can be shifted together and both get knee wall spaces. That would be the finishing touch, as my late grandmother used to say.

Yes, you understood me exactly. The floor plan would change almost completely anyway because we do not want an open loft space. I have done some calculations and also arrived at 1.80 m (5 ft 11 in) (if anyone dares to download the .xlsx in the .zip ). However, all this was calculated with simple “line” walls and without including the thickness of walls and roof extensions. Can you really calculate it that simply? Surely, there must be more to it?

Best regards

The architect submitting the planning permission / building permit must calculate that anyway. You don’t need to maximize the knee wall height down to the last centimeter. My “calculation” with 1.80 m (5 ft 11 in) is not analyzed under a microscope. If you were to exceed the full-story height limit with 1.75 m (5 ft 9 in) – my suggested modification still works with that – I would at least be surprised.

Why should a layperson calculate anything for you here?
Danwood has architects. Those planning to build also need to take the step and talk to the general contractor (GC): they should be able to tell you that.

From a purely technical perspective, the Point 169a is a one-story building... I could repeat #5 if you want, but I won’t.
If you don’t want an open space above, there are other options mentioned.

Alright. I was hoping that someone could calculate everything down to the centimeter using an online calculator or other software that I haven’t been able to find.

In my opinion, linking the house’s footprint with the knee wall height doesn’t make sense. But since this is now law, if the knee wall doesn’t fit, I will ask Danwood how much a bay window or sunroom would cost to achieve the knee wall height I want.

Small house = small knee wall, huge house with a large footprint = two-story building calculated as a single story on paper. Logic?

Thank you all.
