Hello!
Our general contractor (GC) informed us that we need to notch out the house roof in the garage area because the garage roof is higher than the house eaves. Unfortunately, we don’t understand this at all, and the GC didn’t have any picture to illustrate it.
For some background: we are building the garage ourselves (with a friend who is a mason) and were actually ready to start already. Then the GC said we should wait because there were height issues. We can begin once the roof is adjusted. This is now done, and the current instruction is that the house roof must be notched out. Since we have absolutely no knowledge of this topic, my question is whether there is any alternative to notching out the roof? If not, do you have a picture showing what that looks like?

This is the drawing for the building permit / planning permission.
The construction plan does not include a knee wall. However, this is the first time we have seen one.
The roofer must also have seen the drawing for the building permit / planning permission; otherwise, he would not have asked whether the knee wall is really not to be built.

New statement from the general contractor: The Arcon software automatically draws a knee wall to represent the eave height. (Does anyone know about this? Is this correct?)
According to the contract, the eave is at the level of the middle of the concrete ceiling. This would be met if the roof overhang is 50cm (20 inches) and without a knee wall. With a roof overhang of 75cm (30 inches), this is not met.
What is legally binding in this case? The drawing or the eave height?

Caspar202017 Apr 2018 11:22I don’t really see a real knee wall in the building permit drawing. Especially since the marked 25cm (10 inches) starts at the raw concrete slab (meaning the 12cm (5 inches) are subtracted from that—the insulation is not drawn to scale there). That’s why it looks more like a “knee” area.
The execution drawing is a bit more realistic (maybe slightly too thick; since the concrete slab is 18cm (7 inches) and the insulation is only 12cm (5 inches) according to the text).
So, if you were expecting to see a real knee wall, there was already a communication issue with the first drawing.
Furthermore, according to the building permit, the attic is not really usable as storage space if I look at the note on the left saying “not accessible.”
I assume the 12cm (5 inches) of insulation simply lies on the concrete slab. In other words, a finished floor would likely need to be installed on top by the builder. Are you aware of that?

At the time of the drawing, the calculation for the energy heater was not yet available. Now, based on the new information, we can choose whether to insulate only the ceiling with 24cm (9.5 inches) or the ceiling with 18cm (7 inches) plus the space between the joists. We were aware of this beforehand and will do it ourselves.
So, if you draw a line, you can see the following:
In the detailed construction plan, the height up to the start of the roof overhang is slightly below the floor-to-ceiling height of 2.55 meters (8 feet 4 inches)…
In the building permit / planning permission, it is above the floor height, roughly in the middle of the concrete slab…
Whether that difference is 25 cm (10 inches), I wouldn’t want to say… and on one side, you’re given a 25 cm (10 inch) roof overhang… but that means you have to notch out on the other side?… great…
