A question about 10 Degree mono pitched roof and Gable walls

Tēnā koutou (Hello everyone),

Just wondering a bit of a design question around the 10 degrees sloped roof. I am assuming like the other gable ends do you have to have all Wall-S10 1 to 9 blocks?

So it talks about 2.1 m high space, which I am assuming is the lower end of the roof. But I was curious what the high space is on the other side? 3 metre? or 2.4 metre? I could probably calculate it out but I was wondering if someone knew and had worked with it.


Nevermind just found the answer myself on the Design Guide!!
