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

And it also specifies the elevation of the land above sea level. It always comes out to around 9.5 m (31 feet).

Right, now I just need to know how high the knee wall is allowed to be. I hope someone can help with this.

I couldn’t find any restrictions on this. Accordingly, the knee wall height would only be limited by the ridge height.

Let’s assume the following values: raw floor level on the ground floor (GF) at "0.00", floor-to-ceiling height on GF 285 cm (112 inches), floor construction thickness on the upper floor (UF) 16 cm (6 inches) (from which I assume you want to measure the knee wall height), so the finished floor level on the UF is at "3.01" meters (9.88 feet).

If we add your desired knee wall height of 2.00 m (6.56 feet) on top, the total is "5.01" meters (16.44 feet). With a roof pitch of 46° you’d still be within the allowed ridge height of "9.395" meters (30.82 feet). In practice, you will be well below that because you’ll still have the full story right below.

Conclusion: Relax. The regulations for avoiding a full additional story set tighter limits here than the absolute height. For example, with roof pitches of 22° / 25° / 28°, at 2.00 m (6.56 feet) knee wall height you’d reach a room height of 2.30 m (7.55 feet) after only 74 cm (29 inches) / 64 cm (25 inches) / 56 cm (22 inches) distance from the eaves wall—so much too soon. I therefore see, for example, a knee wall height of 1.80 m (5.91 feet) at 25° pitch as a better candidate for your calculations.

But you must not forget one thing. This zoning plan (B Plan) method of referencing heights to standard sea level (NN) prevents you from exceeding the 9.50 meter (31 feet) ridge height by adding fill and thus raising the house’s elevation. If you add 1 meter (3 feet) of fill, you only have 8.5 meters (28 feet) left for the building height. Clear? Karsten

That sounds logical. However, I don’t understand the first calculation from 11ant. In Schleswig-Holstein, the state building code states that the upper floor is considered a full story if it covers at least 75% of the floor area of the story below (and this is based on a height of 2.3 m (7.5 ft) from the floor to the outer roof surface). That’s why a 2-meter (6.6 ft) knee wall is impossible, right? So the Danwood 169A house specifies a 2 m (6.6 ft) knee wall, but that won’t comply, or am I mistaken? In this building area, it seems that the limitation is not the ridge height but the single-story design.

Yes, if I understand correctly, I see the problem as well. What does Danwood say? What would be an alternative? Does it have to be Danwood? If you want timber construction instead of solid wood, take a look at contract vario Ahrensbök near Lübeck. They are smaller, much smaller than Danwood, but they build attractive, very individual houses and are also affordable. K.
