ᐅ Ideal Knee Wall Height for a Gable Roof

Exactly, I think raising the ceiling height from 1 m to 2.80 m (3.3 ft to 9.2 ft) all at once will be too expensive. I will ask about the cost of raising it from 1 m to 1.30 m (3.3 ft to 4.3 ft).

@Bauexperte – what do you think the cost range would be?

@ Tommes

That depends on the size of the building; it’s difficult to say without more details. However, you should be able to compensate for 30cm (12 inches) by slightly reducing the roof pitch.

I would also consider your own height. With a 10m (33 feet) roof length and a 45% roof pitch, a 2m (6 ft 7 in) tall person has a total of 6m² (65 sq ft) less freely accessible space compared to a person who is 1.70m (5 ft 7 in) tall.

Likewise, custom-built wardrobes are likely to be more expensive than standard furniture, which offsets the additional costs associated with two-story buildings.

There is no ideal solution. Anything less than 1.50m (4 feet 11 inches), provided it is permitted by the building permit / planning permission, would be too little for me.

However, the appearance of the house must also be considered – personally, I find houses with very high knee walls (or even fully two-story) with a gable roof unattractive and somehow odd in their symmetry.

They simply don’t fit visually into many development patterns – at least here in the north/west. In the south and east, unfortunately, this is seen more often...

Thanks first of all for the numerous responses. According to the development plan, we are allowed to build up to 2 full stories. However, I agree with Lexmaul79 that 2 full stories don’t look very attractive visually, but that is a matter of taste and utility.

We have now requested a quote from the builder, and the knee wall (dwarf wall) is specified as 1 meter (3 feet 3 inches). The question is what the builder would charge for increasing the knee wall height to, for example, 1.50 meters (4 feet 11 inches). Builders tend to put you in a difficult position with such requests and charge quite a lot for them. Just increasing the basement room height by 10 centimeters (4 inches) from 2.20 meters (7 feet 3 inches) to 2.30 meters (7 feet 6 inches) costs €1200, so I’m curious about the cost of raising the knee wall.
