Hello everyone,
We have an upcoming appointment with the architect. To pass the time, we have had some conversations with a few general contractors.
I am quite surprised by the following statements:
1) For a gable roof without eaves, a solid knee wall must be built – additional cost $12,000
2) A raised ridge or open ridge involves much more insulation material – additional cost $9,000
3) A small T-shaped wall in the bathroom costs an extra $3,000
The first point puzzles me a lot. How is the knee wall constructed in a house with roof overhangs? We had talked about a knee wall height of around 140 cm (55 inches). Unfortunately, I forgot to ask this question during the meeting, so I am looking for an answer here over the weekend.
I find the extra charges for points 2 and 3 somewhat exaggerated, though I can understand that it generally costs more.
Unfortunately, our appointment with the architect is still some time away, so I’m trying to clarify many questions in advance.
Kind regards!

But you could clarify now whether a knee wall and a dwarf wall are seriously intended to be used one after the other here.I want the roof to start only at about 140 - 150 cm (55 - 59 inches) inside the room – I’m not sure which technical term applies here. I had thought both terms referred to the same thing.
A knee wall raises the bottom plate of the roof framing, so the start of the roof slope is already higher up. In contrast, a dwarf wall is a form of false wall that is set back behind a sloped bottom plate starting at floor level until the desired height is reached. However, there are regional architectural differences, meaning that in some areas one method is dominant while the other is almost unknown. This is why the term "drempel" is sometimes also used to refer to a knee wall, leading to considerable confusion in terminology. Where the exterior knee wall (knee wall) is very low, an interior knee wall (dwarf wall) is sometimes built behind it. In my opinion, this rarely makes much sense—just like a roof without eave overhang. You are also welcome to explain why you would want such a design (or do you mean a gable end roof without an overhang, i.e., should it be flush at the verge)?

A knee wall (short wall) raises the height of the wall plate, so the roof slope starts higher up. A dwarf wall, on the other hand, is a type of false wall that steps back behind a roof slope that begins at floor level until the desired height is reached. However, there are regional differences in building culture, and in some areas one method is common while the other is nearly unknown. That’s why people sometimes call a knee wall a dwarf wall—leading to a confusing mix of terms. Where the external knee wall is set quite low, an internal knee wall (dwarf wall) is occasionally built behind it. In my view, this usually makes little sense—similar to a roof without any eaves overhang. You might want to explain why you prefer that: is it actually a roof without an eaves overhang, or do you mean no gable overhang, meaning the roof edge should be flush with the gable end?Roof without eaves overhang = no roof overhang?
If we mean the same thing, then purely for the aesthetic. As you know, I originally didn’t want any sloped roofs, but now it will have some—so at least the house should have a modern look (provided there’s still some budget left for upgrades).
Your example house photo shows no eaves (on the gutter side) or bargeboard (on the gable side); it also has knee walls.
